Realization of a concept as a set of space-time surfaces

The space-time surfaces defined as roots of g_º ...g_º f, where f is a prime polynomial and g(0,0)=(0,0) (here f is an analytic map H=M⁴×CP₂→ C² and g an analytic map C² → C²) form a kind of ensemble of disjoint space-time surfaces. Abstraction means formation of concepts and classically concept is the set of its different instances. Could this union of disjoint space-time surfaces as roots represent a concept classically?

What comes to mind are biological systems consisting of cells: do they represent a concept of a cell? What about a population of organisms? What about an ensemble of elementary particles: could it represent the concept of, say, electrons?

1. Holography= holomorphy principle would be essential for the realization of the geometric correlate of collective quantum coherence. Only initial 3-surfaces defining holographic data matter in holography. The 4-D tangent spaces defining the counterparts for initial velocities cannot be chosen freely. This would force a coherent synchronous motion. Also classical non-determinism would be present. Could it correspond to piecewise constant Hamilton-Jacobi structure with different structure assigned to regions of the space-time surface.
2. The Hamilton Jacobi structure of all members of the ensemble from by the roots of g_º ...g_º f is the same so that they can be said to behave synchronously like a single quantum coherent system. Could the loss of quantum coherence mean splitting: p^k roots forming a coherent structure would decompose to p^k₁ sets with different H-J structures containing p^k-k1 roots. Cognitive ensemble, as a representation of a concept, would decompose to ensembles representing p^k₁ different concepts. Is continual splitting and fusion taking place? Could this conceptualization make possible conceptualized memory: the image of the house would be represented by an ensemble of images of houses as kind of artworks.

I have often enjoyed looking at a crop field in a mild summer wind. To me, the behaviour suggests quantum coherence.

1. Crop field in the wind seems to behave like a single entity. Could the crop field correspond to an abstraction of the notion of crop as a set of its instances, realized as a set of space-time surfaces realized as roots of for g_º...._º f. Also more general composites (g_1)º (g₂)...(g_n)_º f, g_i(0,0)=(0,0), are possible. The roots could also represent the notion of a crop field in wind as a collection of crops, each moving in wind as a particular motion of air around it.
2. Do I create this abstraction as a conceptualization, a kind of thought bubble, or does the real crop field represent this abstraction? Could f correspond to the primary sensory perception and does cognition generate this set (not "in my head" but at my field body) as a hierarchy of iterations and an even more general set of g-composites? Different observers experience crop fields very differently, which would suggest that this is a realistic view.
3. If this set represents the real crop field, there should also be a space-time surface representing the environment and the wind. Could wormhole contacts connect these surfaces representing the concept and the environment to a single coherent whole.

   The usual thinking is that crops from uncorrelated systems and wind as a motion of air causes the crops to move. The coherent motion would correspond to a collective mode in which crops move in unisono and synchronously. What creates this coherent motion? Could macroscopic quantum coherence at the level of the field body be the underlying reason in the TGD Universe?

4. How to describe the wind if one accepts the crop field in wind itself represents the notion of crop in wind? Usually wind is seen as an external force. Coherent motion correlates with the wind locally. What does this mean? How could one include the wind as a part of the system? Wind should affect the crops as roots of g_º...g_º f. Each root should correspond to a specific crop affected locally by the wind. Or should one accept that the concept of crop field in the wind is realized only at the level of cognition rather than at the level of reality?

Classical non-determinism in relation to holography, memory and the realization of intentional action in the TGD Universe

Gary Ehlenberg sent a link to an interesting article with title "'Next-Level' Chaos Traces the True Limit of Predictability" (see this).

Holography, as it is realized in the TGD framework, allows an interesting point of view to the notion of classical chaos. This view is not considered in the article. In the TGD framework, there is also a close relation to the question about how intentions are realized as actions.

1. Holography reduces the initial data at the fundamental level (space-times as surfaces) roughly by one half and space-time surfaces as orbits of 3-surfaces identified as particle like entities are analogous to Bohr orbits for which only initial positions or momenta can be fixed. This increases predictability dramatically. See (see this and this).
2. Holography= holomorphy principle reduces the extremely nonlinear field equations of TGD to algebraic extensions and one obtains minimal surfaces irrespective of action principle if it is general coordinate invariant and involves only the induced geometry. The space-time surfaces are roots of pairs of polynomials or even analytic functions f= (f₁,f₂) of one hyper complex coordinate and 3 complex coordinates of H=M⁴× CP₂. Field equations are more like rules of logic rather than an axiom system. This implies enormous simplification. Solutions are coded by the Taylor coefficients of f₁ and f₂ in an extension E or rationals and for polynomials their number is finite (see this) and this) .

   One obtains new solutions as roots of maps g_º f , where g: C²-->C² is analytic. The iterations of g give rise to the analogs of Mandelbrot fractals and Julia sets so that in this sense classical chaos, or not actually chaos but complexity, emerges. For the iteration of hierarchies P = g_º g .... _º f the complexity increases exponentially since the degree P and the dimension of the corresponding algebraic extension increases exponentially. The roots for the iterates can be however calculated explicitly. The interpretation could be as a classical geometric correlate for an abstraction hierarchy.

3. Already 2-D minimal surfaces representable as soap films are non-deterministic. Soap films spanned by frames are not unique. Now frames would be represented by 3-surfaces and possibly lower-D surfaces representing holographic data. The second, passive, light-like boundary of the causal diamond CD is the basic carrier of holographic data. Also the light-like partonic orbits as interfaces between Minkowskian and Euclidean space-time regions carry holographic data. They serve as building bricks of elementary particles. At 3-D frames minimal surface property fails and field equations on the classical action and express conservation laws for isometry charges for the action in question?

   This is expected to give rise to a finite classical non-determinism. It would be essential for the quantum realization of conscious memory since small state function reductions (SSFRs) do not destroy the classical information about the previous SSFRs (see this). The information is carried by the loci of classical non-determinism having as a counterpart quantal non-determinism assignable to conscious experience.

How could classical non-determinism relate to p-adic non-determinism and to the realization of intentions as transformation of intentions as p-adic space-time surfaces to real space-time surfaces?

1. In adelic physics real and p-adic space-time surfaces are assumed to satisfy essentially the same algebraic field equations. The p-adic and real Taylor coefficients of f=(f₁,f₂) might however relate by canonical identification to guarantee continuous correspondence (see this).

   The conjecture is that ramified primes of polynomials (and their generalization) correspond to preferred p-adic primes appearing in p-adic mass calculations and satisfying p-adic length scale hypothesis (see this) and (see this) .

2. What is the relationship between the classical non-determinism and p-adic non-determinism, tentatively identified as a correlate for the non-determinism of imagination and intentionality? Could one think that in p-adic context intentions classically correspond to the solutions of field equations with the polynomial coefficients having values in the extension E but that being pseudo-constants and constant only inside regions of the space-time surface?

   Is it also possible to obtain real solutions with piece-wise constant Taylor coefficients of f? Is it possible to glue together solutions defined by different f? Does this pose additional conditions to the pseudo constants? If so, realizable intentions correspond to p-adic space-time surfaces, which also have real counterparts. Also real space-time surfaced with Taylor coefficients of f which are constant inside a given space-time region but they could change at the interfaces of two regions.

   A concrete guess is that the gluing of solutions with different choices of f can take place along light-like surfaces since in classical field theories light-like surfaces are seats of non-determinism. Partonic orbits are such surfaces and wormhole contact could define one possible mechanism of gluing together two Minkowskian space-time sheets defined by different choices f.

3. Could the realizabile intentions have as quantum counterparts sequences of small state function reductions (SSFRs)? What the attempt to realize an intention could mean at the quantum level? Could for a given intention only a finite number of SSFRs be possible. After that a big state function reduction (BSFR) would take place and reverse the arrow of time: the sequence of SSFRs as self would "die" or fall asleep. After the second BSFR (wake-up) one would have a new trial for the realization of intention. Since the extension of rationals increases in size, the next real could contain more SSFRs, the updated holographic data could make the life of the new self as an attempt to realize a slightly modified intention longer.

   The hierarchy of g_º g...g_º f would give exponentially increasing complexity and dimension of extension of rationals if g(0,0)= (0,0) so that also f =0. would define one of the roots. Reflective levels would make it easier to realize the intentions by increasing exponentially the number of roots which are in fact disjoint space-time surfaces. One obtains a disjoint union of space-time surfaces as roots unless f is not a prime in the sense that it does not allow a decomposition f = g_º h. Fundamenta space-time surfaces and intentions would be primes in this sense.

See the article Classical non-determinism in relation to holography, memory and the realization of intentional action in the TGD Universe or the chapter Quartz crystals as a life form and ordinary computers as an interface between quartz life and ordinary life?

Revolution in standard model: is the isospin symmetry of strong interactions really violated at quark level?

Phys.org's popular article (see this) tells about a rather surprising finding related to strong interactions. In QCD isospin symmetry is assumed, and the strong interactions in heavy ion collisions should produce equal amounts of charged and neutral kaons. The anomaly was discovered in late 2023, by Wojciech Brylinski who was analyzing data from the NA61/SHINE collaboration at CERN for his thesis. There was a strikingly large imbalance between charged and neutral kaons in argon scandium collisions. Brylinski found that, instead of being produced in roughly equal numbers, charged kaons were produced 18.4 percent more often than neutral kaons. Now this anomaly has been confirmed. NA61/SHINE's data in collisions with 11.9 GeV per nucleon pair (see this) contradicts the hypothesis of equal yields with a 4.7σ significance.

Unless electromagnetic interactions violating the isospin symmetry manage to cause the isospin asymmetry, the key assumption of QCD that electroweak and color interactions are independent, is wrong. Needless to say, this would mean a revolution in the standard model. Here is the abstract of the article.

Strong interactions preserve an approximate isospin symmetry between up (u) and down (d) quarks, part of the more general flavor symmetry. In the case of K meson production, if this isospin symmetry were exact, it would result in equal numbers of charged (K⁺ and K^-) and neutral (K⁰ and K⁰) mesons in the final state. Here, we report results on the relative abundance of charged over neutral K meson production in argon and scandium nuclei collisions at a center-of-mass energy of 11.9 GeV per nucleon pair.

We find that the production of K⁺ and K⁺ mesons at mid-rapidity is (18.4+/- 6.1) per cent higher than that of the neutral K mesons. Although with large uncertainties, earlier data on nucleus-nucleus collisions in the collision center-of-mass energy range 2.6≤s_NN^1/2≤ 200 GeV are consistent with the present result. Using well-established models for hadron production, we demonstrate that known isospin-symmetry breaking effects and the initial nuclei containing more neutrons than protons lead only to a small (few percent) deviation of the charged-to-neutral kaon ratio from unity at high energies. Thus, they cannot explain the measurements.

The significance of the flavor-symmetry violation beyond the known effects is 4.7σ when the compilation of world data with uncertainties quoted by the experiments is used. New systematic, high-precision measurements and theoretical efforts are needed to establish the origin of the observed large isospin-symmetry breaking.

The basic prediction of TGD is that color and electroweak interactions are strongly correlated. Could one understand the anomaly in the TGD framework?

In the following the key ideas of TGD are summarized, the differences between TGD based and standard model descriptions of standard model interactions are discussed, and a simple quantitative model for the isospin anomaly is considered.

Basic ideas of TGD

Consider first the basic ideas of TGD relevant to the model of the isospin anomaly.

1. At the fundamental level, both classical electroweak, color and gravitational fields are geometrized (see this and this). Once the space-time as a 4-surface in H=M⁴× CP₂ is known, all these classical fields are fixed. This choice is unique also from the existence of the twistor lift of the theory: M⁴ and CP₂ are the only 4-D spaces allowing twistor space with K\"ahler structure. Also the number theoretical vision, involving what I call M⁸-H duality (see this), allows only H.

   By general coordinate invariance at the level of H, 4 coordinates of H fix these classical fields so that very strong correlations between classical fields emerge. In particular, electroweak and color fields are strongly correlated. This means a profound difference from QCD.

2. The notion of a particle generalizes at topological and geometric level. Point-like particles are replaced by 3-D surfaces. Fermionic degrees of freedom correspond to second quantized free spinor fields of H restricted to the space-time surface. Only leptons and quarks are predicted and family replication phenomenon is understood in terms of the genus of a apartonic 2-surface (see this). The light-like orbit of the partonic 2-surfaces carries fermion and antifermion lines identified as boundaries of strong world sheets in the interior of the space-time surface. In the simplest model, one can assign gauge boson quantum numbers to fermion-anti-fermion pairs and the quark model of hadrons generalizes.

The construction of Quantum TGD relies on two complementary visions of physics: physics as geometry and physics as number theory.

1. The construction of quantum TGD as a geometrization of physics leads to the notion of World of Classical Worlds (WCW) consisting of space-time surfaces in H obeying holography necessary for getting rid of path integral plagued by divergences. Holography means that 3-D data -a 3-surface - fixes the space-time surface as analog of Bohr orbit for 3-D particles so that in geometric degrees of freedom TGD is essentially wave mechanics for 3-D particles.

   WCW spinors correspond to Fock states for the second quantized fermions of H and gamma matrices are super generators for the infinite-D symmetries of WCW. A huge generalization of conformal symmetries of string models and symplectic symmetries for H is involved.

   Conformal symmetries emerge from holography= holomorphy vision leading to an exact solvability of classical TGD. Space-time surfaces are roots for pairs f=(f₁,f₂) of analytic functions H→ C² of one hypercomplex coordinate and 3 complex coordinates of H. The field equations are extremely nonlinear partial differential equations but reduce to purely algebraic equations. As long as the classical action is general coordinate invariant and depends only on the induced fields, the space-time surfaces are minimal surfaces irrespective of the choice of the action. The maps g=(g₁,g₂): C²→ C² act as dynamical symmetries. The hierarchies of polynomials in extensions E of rationals define hierarchies of solutions of field equations.

2. Number theoretical vision emerged first from the p-adic mass calculations leading to excellent predictions for particle masses. The basic assumption was conformal invariance and p-adic thermodynamics allowing to calculate mass squared as a p-adic thermal expectation mapped to a real mass squared by canonical identification (see this). p-Adic length scale hypothesis stating that physically preferred primes p∼ 2^k, was an essential assumption. In particular, Mersenne primes and Gaussian Mersenne primes satisfy this condition. Also powers of small primes q>2, in particular q=3, can be considered in the p-adic length scale hypothesis (see this).

   Both the pairs (f₁,f₂) and (g₁,g₂) allow to identify candidates for p-adic primes as analogs of ramified primes associated with algebraic extensions of E, in particular those of rationals.

How does the TGD view of standard model interactions differ from the standard model view?

TGD view of standard model interactions differs in several respects from the standard model view?

1. In TGD, elementary particles correspond to closed monopole flux tubes as analogs of hadronic strings connecting two Minkowskian space-time sheets by Euclidean wormhole contacts. The light-like orbits of wormhole throats (partonic orbits) carry fermions and antifermions at light curves located at light-like 3-surfaces, which define interfaces between Minkowskian string world regions and Euclidean regions identified as deformed CP₂ type extremals.
2. The basic difference at the level of H spinor fields is that color quantum numbers are not spin-like but are replaced with color partial waves in CP₂. Color degrees of freedom are analogous to the rotational degrees of freedom of a rigid body. An infinite number of color partial waves emerges for both quarks and leptons. In TGD, color and electroweak degrees of freedom are strongly correlated as is also clear from the fact that color symmetries correspond to the non-broken symmetries as isometries of CP₂ and electroweak symmetries correspond to the holonomies of CP₂, which are automatically broken gauge symmetries.

   The spectrum of color partial waves is different for U and D type quarks and for charged leptons and neutrinos. The triality of the partial wave is zero for leptons and 1 resp. -1 for quarks resp. antiquarks. At the level of fundamental fermions, which do not correspond as such to fermions as elementary particles, there is a strong violation of isospin symmetry.

The physical states are constructed using p-adic thermodynamics (see this and this) for the scaling generator L₀ of the conformal symmetries extended to the space-time level and involve the action of Kac-Moody type algebras. The basic challenge of the state construction of the physical states is to obtain physical states with correct color quantum numbers.

1. General irrep of SU(3) is labelled by a pair (p,q) of integers, where p resp. q corresponds intuitively to the number of quarks resp. antiquarks. The dimension of the representation is d(p,q)= (1/2)(p+1)(q+1)(p+q+2)

   The spinors assignable to left and right handed neutrino correspond to representations of color group of type (p,p), where the integers and only right-handed neutrino allows singlet (0,0) as covariantly constant Cq spinor mode. (1,1) corresponds to octet 8. Charged leptons allow representations of type (3+p,p): p=0 corresponds to decuplet 10. Note that (0,3) corresponds to 10.

   Quarks correspond to irreps of type obtained from leptons by adding one quarks that is replacing (p+3,p) with (p+4,p) (p=0 gives d=20) or (p,p) with (p+1,p) (p=1 gives d=42). Antiquarks are obtained by replacing (p,p+3) replaced with (p,p+4) and (p,p) with (p,p+1).

2. Physical leptons (quarks) are color singlets (triplets). One can imagine two ways to achieve this.

   Option I: The conformal generators act on the ground state defined by the spinor harmonic of H. Could the tensor product of the conformal generators with spinor modes give a color singlet state for leptons and triplet state for quarks? The constraint that Kac-Moody type generators annihilate the physical states, realizing conformal invariance, might pose severe difficulties.

   In fact, TGD leads to the proposal that there is a hierarchical symmetry breaking for conformal half-algebras containing a hierarchy of isomorphic sub-algebras with conformal weights coming as multiplets of the weights of the entire algebra. This would make the gauge symmetry of the subalgebra with weights below given maximal weight to a physical symmetry.

   Option II: The proposal is that the wormhole throats also contain pairs of left- and right-handed neutrinos guaranteeing that the total electroweak quantum numbers of the string-like closed monopole flux tube representing hadron vanishes. This would make the weak interactions short-ranged with the range determined by the length of the string-like object.

   One must study the tensor products of ν_Lν_R and ν_Lν_R states with the leptonic (quark) spinor harmonic to see whether it is possible to obtain singlet (triplet) states. The tensor product of a neutrino octet with a neutrino type spinor contains a color singlet. The tensor product 8⊗ 8 = 1+8_A+8_S+10+10 +27 contains 10 and its tensor product with 10 for quark contains a color triplet.

Number theoretic vision is highly relevant for the model of isospin anomaly.

1. p-Adic length scale hypothesis can be applied to quarks. The empirical estimates for the masses of u and d type current quarks vary in wide range and have become smaller during years. One estimate (see this is that u quark has mass in the range 1.7-3.3 MeV and d has mass in the range 4.1-5.8 MeV. The estimate represented in Wikipedia (see this) is consistent with this estimate.

   p-Adic length scale hypothesis suggests that the p-adic mass scales satisfy m(d)/m(u)=2 so that p(d)/p(u)=1/4 and k(d)= k(u)-2. For electron the p-adic mass scale corresponds to the Mersenne prime M₁₂₇= 2¹²⁷-1 with k(e)=127. m(u)∼ 4m_e suggests k(u)=127-4=123 and k(d)=k(u)-2= 121.

2. The number theoretic vision (see this) implies that coupling constant evolution is discretized and the values of coupling parameters correspond to extensions of rationals characterizing the classical solutions of field equations as roots (f₁,f₂)=(0,0). This conforms with the general vision that the TGD Universe is quantum critical. The quantum criticality conforms with the generalized conformal symmetries consistent with the holography= holomorphy vision. p-Adic primes are proposed to correspond to the ramified primes associated to the polynomial pairs and for rational primes one obtains ordinary p-adic primes assignable to ordinary integers.
3. Since u and d quarks correspond to different p-adic length scales they must correspond to different p-adic primes and presumably also to different extensions of rationals. Therefore the color couplings of gluon to a u quark pair and d quark pair are different. This would imply the violation of isospin asymmetry of strong interactions. One expects that the gluon coupling strength α_s depends on the p-adic length scale of the quark, and the guess, motivated by QFTs, is that the dependence is logarithmic.

How could one understand the isospin violation of strong interactions?

1. The formation of K⁺=us and K⁰= ds involves strong interaction and therefore exchange of gluons between u and s for K⁺ and d and s for K⁰. The emission vertex is proportional to α_s. In TGD, the gluon corresponds to a superposition of uu, dd pairs and also pairs of higher quark generations. Only the ud couples to K⁺ and dd couples to K⁰ in the vertex. The gluon exchange vertex is analogous to a vertex for the annihilation of gluon to a fermion pair and the different p-adic length scales for u and d imply that the analog of QCD coupling strength α_s is different ud and dd.
2. For general coupling constant evolution the dependence of length scale is logarithmic. The amplitude for the exchange of gluon characterized by α_s should be larger for uuug vertex than ddg vertez. The p-adic length scale for u should be by a factor 2 longer than for u. If the coupling constant is proportional to the logarithm, one has α_s \propto log₂(p(q))= k(q). This would give for the ratio Δ g_s/g_s(u)= (Δ g_s(u)-g_s (d))/g_s(u) the estimate Δ g_s/g_s(u)∼eq (k(u)-k(d))/k(u)∼ 4/123∼ 3.3 percent. For α_s this would give Δ α_s/α_s ∼ 6.6 per cent. This is roughly by a factor 1/3 times smaller than the empirical result 18.4 percent. k(u)-k(d)= 2 → 6 giving k(d)= 123-6=117 would produce a better result and give m(d)∼ 16 MeV. This looks non-realistic.
3. g_s can also depend on the em charge of the quark. The dependence must be very weak and logarithmic dependence is suggestive. The dependence can be only on the square of the em charge. What is wanted is Δ k_eff(u)-k_eff(d) → Δ k_eff= k(u)-k(d)-4. The values of x(q)= (3Q_em(q))² for U resp. D type quarks are x(q)= 4=2² resp. x_q= 1 and therefore powers of 2. The simplest quess is that g_s is of the form g_s(q) ∝ log₂(x(q) × 2^k(q)). This gives k_eff(u)=k(u)+2 and k_eff(d)= k(d) giving k_eff(u)-k_eff(d)= k(u)-k(d)+2=4. This would predict (g_s(u)-g_s(d))/g(d)∼ 6.6 percent and (α_s(u)-α_s(d))/α(d)∼ 13.2. This is about 71 per cent from the empirical value 18.4 percent. The rather artifical dependence x(q)= (3Q_em(q))⁴ would give 19.2.

Oxygen discovered in the most distant known galaxy

Oxygen is discovered in the most distant known galaxy at distance corresponding to the age 300 million years for the Universe (see the popular article). There are two articles related to the finding (see this and this). Researchers had thought that at that time the universe was still too young to have galaxies ripe with heavy elements. However, the two ALMA studies indicate JADES-GS-z14-0 has about 10 times more heavy elements, in particular oxygen, than expected. This does not conform with the standard story about the evolution of stars and the view of the formation of galaxies.

The conservative view (see this) is that everything conforms with the expectations: the heavy elements have been produced in very early massive galaxies showing as red dots in JWST data containing very massive and short-lived stars. The problem is that the origin of these very massive very early galaxies is far from being understood. The proponents of the standard cosmology are desperately defending the standard cosmology against empirical findings challenging it.

My own view is that the various anomalies leave only one conclusion: the views about astrophysics, galaxies, and cosmology based on the general relativistic notion of space-time are badly in need of updating. TGD suggests a dramatic modification of the notion of space-time leading to a new view about cosmic evolution, and galactic and astrophysics. Cosmic string like objects unstable against thickening to monopole flux tubes would be relevant for physics in all scales and also for the formation of galaxies, stars and even planets (see for instance this, this and this).

The zero energy ontology (ZEO) forced by TGD and solving the basic problem of quantum measurement theory predicts quantum coherence in arbitrarily long scales and that the arrow of time changes in "big" state function reductions (BSFRs) as counterparts of the ordinary SFRs. ZEO could explain stars and galaxies older than the Universe and could be highly relevant concerning the understanding of the findings of JWST. It could also allow us to understand why highly evolved galaxies appear in the very early Universe. The evolutionary age of the galaxy could be much longer than the usual age due to the living forth and back in geometric time.

In the following I will discuss only the possible role of the TGD based view of stars in attempts to understand the findings. Of course, the recent view of stellar evolution is regarded as more or less final. There are however numerous anomalies challenging it (see this). Could the recent findings mean an additional challenge for the model? The TGD based view of space-time suggests a rather radical view of the stellar evolution motivated by numerous anomalies of the standard model.

1. Nuclei would be formed, not in the stellar cores, but at the surfaces of stars, covered by monopole flux which give rise to what I call M₈₉ nuclear strings (see this). Also ordinary nuclei would be monopole flux tubes containing nucleons (see this). The monopole flux tubes carrying M₈₉ nuclei and connecting the Sun to the galactic nucleus or blackhole could have time independent dynamics in a good approximation.

   M₈₉ monopole flux tubes would decay by reconnection to flux loops and M₈₉ nucleons would decay to ordinary nucleons by a process that I call p-adic cooling (see this and this). In this cascade-like process process the p-adic prime characterizing the nucleon and near to a power 2 would gradually decrease and the mass scale of the M₈₉ hadrons would be reduced octave by octave and eventually reach M₁₀₇ mass scale which corresponds to the ordinary nucleons. This process would liberate energy and also give rise to anomalous gamma rays with energy range extending to TeV energies: these gamma rays indeed show up themselves as anomalies. It would also create solar wind and generate solar wind.

   M₈₉ nuclei could decay M₁₀₇ nuclei or to M₁₀₇ nucleons, which could fuse to dark M₁₀₇ nuclei by dark fusion and transform to ordinary nuclei liberating almost all of the ordinary nuclear binding energy. At the surface of the star a slowly evolving equilibrium would emerge and give rise to the aging of the star. The abundances of various atoms would depend on the age. The difference with respect to the standard model would be that nuclei at the surface of the Sun would not originate from the solar core and that hot fusion would be replaced with dark fusion explaining the "cold fusion" (see this).

2. The absorption line spectrum of the star is determined by the surface temperature of the star (see this). The nearby environment absorbs part of the radiation. The surface temperature and the metallicity of the star, now the metallicity of its surface, can be deduced from its spectrum.
3. TGD view differs from the standard picture since the nuclei are not endlessly recirculated via the stellar cores but produced at the surfaces of the stars from M₈₉ nuclei. The nuclei from the remnants of earlier stars can end up on the surface of the new stars but how important this contribution is, is not clear.
4. The finding that the very early Universe contains high metallicity stars is consistent with the TGD view. They could be massive stars believed to have existed in very massive galaxies in the very early Universe. The TGD based model should be able to explain stellar generations and also the empirical absence of population III stars representing the hypothetical first generation stars containing mostly hydrogen and helium. A possible explanation is that dark fusion also produces heavier elements and they emerge from the very beginning. This would also explain the recent evidence for high abundances of heavier elements. Note that population II stars old and metal-poor. Population I stars relatively young and metal-rich.

   In the standard model young stars are identified as later stellar generations and have high metallicity due to the metals produced in the fusion in the core. The initial state of the core for the fusion would be determined by the abundances of the metals produced in supernova explosions of the earlier star generations.

   In the TGD framework, one is forced to challenge the notion of stellar generations. Could the metallicity at the surface of a young star be always high and could it decrease during aging so that old stars with a low metallicity would have evolved from stars with higher metallicity? Why would metallicity be reduced with aging? Gravitational binding energy is larger for the heavier nuclei. Could the lighter nuclei remain near the surface and the heavier nuclei sink towards the core as in the case of Earth?

p-Adic length scale hypothesis and Mandelbrot fractals

This post (see this) is a continuation to the previous suggesting a definition of generalized p-adic numbers in which functional powers of map g₁: C²→ C² for which g₁ is a prime polynomial P_p with coefficients in extension E of rationals with degree low than p of P would define the analogs of powers of p-adic prime. For simplicity, one can restrict E to rationals. The question was whether it might be possible to understand p-adic primes satisfying p-adic length scale hypothesis as ramified primes appearing as divisors of the discriminant of the iterate of g₁=P.

Generalized p-adic numbers as such are a very large structure and the systems satisfying the p-adic length scale hypothesis should be physically and mathematically special. Consider the following assumptions.

1. Consider generalized p-adic primes associated restricted to the case when f₂ is not affected in the iteration so that one has g=(g₁,Id) and g₁= g₁(f₁) is true. This would conform with the hypothesis that f₂ defines the analog of a slowly varying cosmological constant. If one assumes that the small prime corresponds to q=2, the iteration reduces to the iteration appearing in the construction of Mandelbrot fractals and Julia sets. If one assumes g₁= g₁(f₁,f₂), f₂ defines the analog of the complex parameter appearing in the definition of Mandelbrot fractals. The values of f₂ for which the iteration converges to zero would correspond to the Mandelbrot set having a boundary, which is fractal.
2. For the generalized p-adic numbers one can restrict the consideration to mere powers g₁ⁿ as analogs of powers pⁿ. This would be a sequence of iterates as analogs of abstractions. This would suggest g₁(0)=0.
3. The physically interesting polynomials g₁ should have special properties. One possibility is that for q=2 the coefficients of the simplest polynomials make sense in finite field F₂ so that the polynomials are P₂(z== f₁,ε) =z² +ε z= z(z+ε), ε= +/- 1 are of special interest. For q>2 the coefficients could be analogous to the elements of the finite field F_q represented as phases exp(i2π k/3).

Consider now what these premises imply.

1. Quite generally, the roots of P° ⁿ(g₁) are given R(n)= P°^(-n)(0). P(0)=0 implies that the set R_n of roots at the level n are obtained as R_n= R_n(new)∪ R_n-1, where R_n(new) consist of q new roots emerging at level n. Each step gives q^n-1 roots at the previous level and q^n-1 new roots.
2. It is possible to analytically solve the roots for the iterates of polynomials with degree 2 or 3. Hence for q= 2 and 3 (there is evidence for the 3-adic length scale hypothesis) the inverse of g₁ can be solved analytically. The roots at level n are obtained by solving the equation P(r_n)= r_n-1,k for all roots r_n-1,k at level n-1. The roots in R_n-1(new) give q^n-1 new roots in R_n(new).
3. For q=2, the iteration would proceed as follows:

   0→ {0, r₁} → {0,r₁} ∪ {r₂₁, r₂₂} → {0,r₁} ∪ {r₂₁, r₂₂}∪ {r₁₂₁, r₂₂₁, r₁₂₂, r₂₂₂} → ... .

4. The expression for the discriminant D of g₁°ⁿ can be deduced from the structure of the root set. D satisfies the recursion formula D(n)= D(n,new)× D(n-1) × D(n,new;n-1). Here D(n,new) is the product

   ∏_{ri,rj ∈ D(n,new)}(r_i-r_j)²

   and D(n,new;n-1) is the product

   ∏_{ri∈ D(n,new),rj ∈ D(n-1)}(r_i-r_j)².

5. At the limit n→ ∞, the set R_n(new) approaches the boundary of the Fatou set defining the Julia set.

As an example one can look at the iteration of g₁(z)= z(z-ε).

1. The roots of z(z-ε)=0 are {0,r₁}={0,ε}. At second level, the new roots satisfy z(z-ε)=r₁=ε given by {(ε/2)(1 +/- (1+4r₁)^1/2}. At the third level the new roots satisfy z(z-ε)=r₂ and given by {(ε/2)(1 +/- (1+4r₂)^1/2}.
2. The points z=0 and z=ε are fixed points. Assume ε=1 for definiteness. The image points w(z)= z(z-ε) satisfy the condition |w(z)/z|=|z-1|. For the disk D(1,1):|z-1| ≤ 1 the image points therefore satisfy |w| ≤ |z| ≤ 2 and belong to the disk D(0,2): |z |≤ 2.

   For the points in D(0,2)\ D(1,1) the image point satisfies |w|=|z-1||z| giving |z|-1 ≤ |w| ≤ |z|+1. Inside D(0,2)\ D(1,1) this gives 0 ≤|w| ≤ 3. Therefore w can be inside D(2,0) including D(1,1) also inside disk D(0,3).

   For the points z outside D(2,0)|w|=|z-1||z| ≥ 2. So that the iteration leads to infinity here.

3. For the inverse of the iteration relevant for finding the roots of f^°(-n) leads from the exterior of D(2,0) to its interior but cannot lead from interior to the exterior since in this case f would lead to exterior to interior. Hence the values of the roots w_n in ∪_n f°^(-n) belong to the disc D(2,0).

The conjecture deserving to be killed is that the discriminant D for the iterate has Mersenne primes as factors for primes n defining Mersenne primes M_n= 2ⁿ-1 and that also for other values of n D contains as a factor ramified primes near to 2ⁿ.

Dark energy weakens

Quanta Magazine post (see this) tells about the evidence, found by DESI collaboration, that dark energy is getting weaker. These findings challenge the very notion of dark energy, which is also theoretically problematic. There is the problem whether the dark energy corresponds to a modification of the gravitational part of the action obtained by replacing the curvature scalar by adding a volume term or a modification of the matter part of the action corresponding to exotic particles, quintessence, with a negative pressure.

In Big Think (see this) there is article discussing in detail the claim about the claimed weakening of dark energy (see this). The article describes in detail their constraints on the $\Lambda$CDM model. It becomes clear that standard cosmology is a good parametrization of huge amounts of data but has a lot of problems and that the notion of dark energy is far from being elegant. The basic empirical inputs are as follows.

1. Cosmic microwave background (CMB) provides information about the basic parameters of the standard cosmology such as its age, the value of Hubble constant characterizing the expansion rate, and density matter. This information allows us to identify several anomalies. For instance, the Hubble constant seems to have two slightly different values. It would seem that Hubble constant depends on length scale but the notion of scale is lacking from the standard cosmology.
2. The finding that the radiation from supernovae of type I is weaker than expected led to the conclusion that cosmic expansion is accelerating. Cosmological constant characterizing dark energy density would at least parametrix the acceleration expansion in the general relativistic framework.
3. Baryonic acoustic oscillations (BAO) provide information about the large scale structure of the Universe and BAO led in the recent study to the conclusion that dark energy is weakening. BAO has also led to the conclusion that the density of baryonic matter is decreasing: as if baryons were disappearing. Are these two phenomena different aspects of the same phenomenon?

In TGD, the new view of space-times as 4-D surfaces in H=M⁴×CP₂, predicts the analogy of cosmological constant as well as its weakening.

1. String tension characterizes the energy density of a magnetic monopole flux tube, a 3-D surface in H=M⁴×CP₂. String tension contains a volume part (direct analog of Λ) and Kähler magnetic part and it is a matter of taste whether one identifies the entire string tension or only the volume contribution as counterpart of Λ. In the primordial cosmology (see this), cosmic string sheets have 2-D M⁴ projection and 2-D CP₂ projection.
2. Cosmic strings are unstable against the thickening of their 2-D M⁴ projection, which means that the energy density is gradually reduced in a sequence of phase transitions as thickenings of the cosmic string so that they become monopole flux tubes and give rise to galaxies and stars. The energy of cosmic strings is transformed to ordinary particles. This process is the TGD analog of inflation. No inflaton fields are required.
3. The string tension is gradually reduced in these phase transitions and in this sense one could say that dark energy is weakened. For instance, for hadronic strings it is rather small as compared to the original value of string tension during the primordial phase dominated by cosmic strings, at the molecular level the string tension of cosmic strings is really small.
4. The primordial string dominated phase was followed by a transition to the radiation dominated cosmology and emergence of Einsteinian space-time with 4-D M⁴ projection so that general relativity and quantum field theory became good approximations explaining a lot of physics. Quantum field theory approximation cannot however explain the structures appearing in all scales and here monopole flux tubes are necessary.
5. TGD also predicts a hierarchy of effective Planck constants labelling phases of the ordinary matter behaving like dark matter in many respects. These phases would be quantum coherent in arbitrarily long scales. They would reside at the magnetic bodies consisting of monopole flux tubes and define a number theoretic complexity hierarchy highly relevant in quantum biology. The transformation of ordinary matter to this kind of dark matter would explain the observed apparent disappearance of baryons during cosmic evolution. In primordial cosmology cosmic strings as 4-D objects with 2-D M⁴ projection would dominate: during this period one cannot speak of Einsteinian space-time as space-time surfaces with 4-D M⁴ projection.

One can try to translate these analogies to a more detailed quantitative view of dark energy and dark matter.

1. The energy of cosmic string contains two contributions: volume contribution and Kähler magnetic contribution. Their sum defines the galactic dark matter (see this), whose portion is about 26 percent of cosmic energy density, and it is concentrated at cosmic strings. Ordinary matter, about 5 percent of energy density emerges in the thickening of these cosmic strings as they form local tangles. The liberated energy transforms to ordinary matter. This is the TGD counterpart of inflation and cosmic strings carry the counterpart of matter assigned with the vacuum expectations of inflation fields.
2. What about the dark energy forming 85 percent of cosmic energy density? Does dark energy correspond to the energy associated with Minkowski space-time sheets as the energy associated with the volume action with Käher magnetic part being negligible. Could the volume contribution dominate or are the contributions of the same size scale? The cosmological constant would have a spectrum being inversely proportional to the p-adic length scale characterizing these space-time sheets. The value of the cosmological constant would not depend on time but on the scale of the space-time sheet and would decrease as a function of the scale. This might explain the latest findings if they are true.
3. One can ask whether only magnetic flux tubes and sheets are present at the fundamental level and whether cosmological constant corresponds to the energy assignable to large enough monopole flux tubes. Already flux tubes of the thickness of neuron size correspond to the extremely small value of cosmological constant deduced from cosmology. Also hadronic string tension corresponds to a particular value of cosmological constant.

See for instance the article About the recent TGD based view concerning cosmology and astrophysics or the chapter with the same title.

Witt vectors and polynomials and the representation of generalized p-adic numbers as space-time surfaces

We have had very inspiring discussions with Robert Paster, who advocates the importance of universal Witt Vectors (UWVs) and Witt polynomials (see this) in the modelling of the brain, have been very inspiring. As the special case Witt vectors code for p-adic number fields. Witt polynomials are characterized by their roots, and the TGD view about space-time surfaces both as generalized numbers and representations of ordinary numbers, inspires the idea how the roots of for suitably identified Witt polynomials could be represented as space-time surfaces in the TGD framework. This would give a representation of generalized p-adic numbers as space-time surfaces.

Could the prime polynomial pairs (g₁,g₂): C²→ C² and (f₁,f₂): H=M⁴× CP₂→ C² (perpaps states of pure, non-reflective awareness) characterized by small primes give rise to p-adic numbers represented in terms of space-time surfaces such that these primes could correspond to ordinary p-adic primes? Same question applies to the pairs (f₁,f₂) which are functional primes.

1. Universal Witt vectors and polynomials can be assigned to any commutative ring R, not only p-adic integers. Witt vectors X_n define sequences of elements of a ring R and Universal Witt polynomials W_n(X₁,X₂,...,X_n) define a sequence of polynomials of order n. In the case of p-adic number field X_n correspond to the pinary digit of power pⁿ and can be regarded as elements of finite field F_p which can be also mapped to phase factors exp(ik 2π/p). The motivation for Witt polynomials is that the multiplication and sum of p-adic numbers can be done in a component-wise manner for Witt polynomials whereas for pinary digits sum and product affect the higher pinary digits in the sum and product.

   In the general case, the Witt polynomial as a polynomial of several variables can be written as W_n(X₀,X₁,...)=\sum_{d\mid n} d X_d^{n/d, where d is a divisor of n, with 1 and n included.}

2. The function pairs (f₁,f₂): M⁴→ C² define a ring-like structure. Product and sum are well-defined for these pairs. The function pair related to (f₁,f₂) by a multiplication by a function pair (h₁,h₂), which vanishes nowhere in CD, defines the same space-time surface as the original one is equivalent with the original one. Note that also the powers (f₁ⁿ,f₂ⁿ) define the same 4-surfaces as (f₁,f₂).

   The degrees for the product of polynomial pairs (P₁,P₂) and (Q₁,Q₂) are additive. In the sum, the degree of the sum is not larger than the larger degree and it can happen that the highest powers sum up to zero so that the degree is smaller. This reminds of the properties of non-Archimedean norm for the p-adic numbers. The zero element defines the entire H as a root and the unit element does not define any space-time surface as a root.

   For the pairs (g₁,g₂) also functional composition is possible and the degrees are multiplicative in this operation.

3. Functional primes (f₁,f₂) define analogs of ordinary primes and the polynomials with degrees associated with the 3 complex coordinates of H below the primes associated with these coordinates are analogous to pinary digits. Also the pairs (g₁,g₂) define functional primes both with respect to powers defined by element-wise product and functional composition.

Generalization of Witt polynomials

Could a representation of polynomials, in particular the analogs of Witt polynomials in terms of their roots in turn represented in terms of space-time surfaces, be a universal feature of mathematical cognition? If so, cognition would really create worlds! In Finland we have Kalevala as a national epic and it roughly says that things were discovered by first discovering the word describing the thing. Something similar appears in the Bible: "In the beginning was the Word, and the Word was with God, and the Word was God. Word is world!

Could p-adic numbers or their generalization for functional primes (f₁,f₂) have a representation in terms of Witt polynomials coded by their roots defining space-time surfaces.

1. W_n is a polynomial of n arguments X_k whereas the arguments of the polynomials defining space-time surfaces correspond to 3 complex H coordinates. In the p-adic case the factors d are powers of p. X_d are analogous to elements of a finite field as coefficients of powers of p.
2. There are two cases to consider. The Witt polynomials assignable to the space-time surfaces (f₁,f₂)=(0,0): H→ C² using element-wise sum and product. For the pairs g=(g₁,g₂)=(0,0): C²→ C² one can consider sum and element-wise product giving gⁿ= (g₁ⁿ,g₂ⁿ) and the sum or functional composition giving g(g(...g)...). The latter option looks especially attractive. One reason is that by the previous considerations the prime surface pairs (f₁,f₂) might be two simple. For instance the iterations (g₁,g₂) with prime degree 2,3,.. could give a justification for the p-adic length scale hypothesis and its generalization.

Consider first the pairs (f₁,f₂): H→ C².

1. If the space-time surface (f₁,f₂)=(0,0) is prime with respect to the functional composition f→ g(f), it naturally generalizes the p-adic prime p so that one would have p^k→ (f₁,f₂)^k and n₁=n₂.

   X_k are the analogs of pinary digits as elements of finite fields. Could they correspond to polynomials with the 3 degrees smaller than the corresponding prime degree assignable to the prime polynomial (f₁,f₂)?

2. With these identifications it might be possible to generalize the Witt polynomials to their functional variants as such and find its roots represented as space-time surfaces. These surfaces would represent the functional analog of the p-adic number field. One can also assign to the functional p-adic numbers ramified primes defining ordinary p-adic primes. Each functional p-adic number would define ramified primes and these would correspond to the p-adic primes.
3. f_i are labelled by 3 ordinary primes p_r(f_i), r=1,2,3, rather than single prime p and by the earlier argument one can restrict the condition to f₁.

   Every functional p-adic number corresponds to its own ramified primes determined by the roots of its Witt polynomial. There is a huge number of these generalized p-adic numbers. Could some special functional p-adic primes correspond to elementary particles? The simplest generalized p-adic number corresponds to a functional prime and in this case the surface in question would correspond to (f₁,f₂)=(0,0) (could this be interpreted as stating the analog of mod ~p=0 condition). These prime surfaces might be too simple and it is not easy to understand how the large values of p--adic primes could be understood.

One can ask whether the analogs of ramified primes for the Witten polynomials assignable abstraction hierarchies g(g(...(f)...) and powers gⁿ=(g₁ⁿ,g₂ⁿ) for which the degree of the polynomials is n×p, p the prime assignable to g.

1. The ramified primes for the Witten polynomials for g(g(...(f)...) and gⁿ defining analogs of powers pⁿ of p-adic numbers. Note that the roots of g(g(...(f)...) are a property of g(g(...(g)...) and do not depend on f in case that they exist as surfaces inside the CD.
2. The interesting question is whether and how the ramified primes could relate to the ramified primes assignable to a generalized Witt polynomial W_n. The iterated action of prime g giving g(g(...(f)...) is the best candidate. There is hope that even the p-adic length scale hypothesis could be understood as a ramified primes assignable to some functional prime. The large values of p-adic primes require that very large ramified primes for the functional primes (f₁,f₂). This would suggest that the iterate g(g....g(f)...) acting on prime f is involved. For p∼ q^k, k^th power of g characterized by prime g is the first guess.

Ytterbium anomaly

Sabine Hossenfelder talked about a very interesting nuclear physics anomaly known as Ytterbium anomaly (see this). There is a Phys. Rev. Lett. article about this anomaly titled "Probing New Bosons and Nuclear Structures with Ytterbium Isotope Shifts" (see this). What makes this anomaly so interesting is that it is reported to have a significance level of 23 sigmas! 5 sigmas is usually regarded as the significance, which makes it possible to speak of a discovery.

1. Ytterbium (see this) is a heavy nuclear with charge Z=70 and mass number of A=173 so that neutron number would be N= 103 for the most general isotope (it seems that the definition of isotope number varies depending on whether its defined in terms of mass or the actual number of nucleons). The mass numbers of Yb vary in the range 168-176. Ytterbium is a rare earth metal with electron configuration [Xe] 4f¹⁴6s^2.
2. The electronic state seems to be very sensitive to the number of neurons in Yb and this is why Yb is so interesting from the point of view of atomic physics. The anomaly is related to the isotope shift for the electron energies. So called Frequency Comb method amplifies the mismatch with the standard theory. Mismatch indeed exists and could be understood in terms of a new particle with a mass of few MeVs.
3. There is an earlier anomaly known as Atomki anomaly (see this and this) explained by what is called X boson in mass range 16-17 meV and the Yb anomaly could be explained in terms of X boson (see this).

I have discussed the X boson in the TGD framework and proposed that it could be a pion-like state (see this).

1. The proposed model provides new insights on the relation between weak and strong interactions. One can pose several questions. Could X could be a scaled variant of pion? Or could weak interaction physics have a scaled down copy in nuclear scale?
2. The latter option would mean that some weak boson could become dark and its Compton length would be scaled up by factor h_eff/h to nuclear p-adic length scale. I have proposed a scaled up copy of hadron physics characterized by Mersenne prime M₈₉ with a mass scale, which is 512 higher than for ordinary hadrons with M₁₀₇. In the high energy nuclear collisions in which quark-gluon plasma is believed to be created at quantum criticality, M₈₉ hadrons would be generated. They would be dark and have h_eff/h=512 so that the scaled up hadronic Compton length would be the same as for ordinary hadrons (see this and this). M₈₉ hadron physics would explain a large number of particle physics anomalies and there is considerable evidence for it. The most radical implications of M₈₉ hadron physics would be for solar physics (see this).

Could also weak interaction physics have dark variants at some kind of quantum criticality and could the Yb anomaly and Atomki anomaly be understood as manifestations of this new physics.

1. Weak bosons are characterized by p∼ 2^k, k=91, from the mass scale of weak bosons. A little confession: for a long time I believed that the p-adic mass scale of weak bosons corresponds to k=89 rather than k=91. For the Higgs boson the mass scale would correspond to M₈₉. TGD also predicts a pseudoscalar variant π_W of the Higgs boson. Could the dark variant of the pseudoscalar Higgs boson π_W with Compton length assignable to the X boson be involved?
2. The scaled up weak boson should have a p-adic length scale which equals nuclear length scale or is longer. Dark π_W could become effectively massless below its Compton length. The mass of X boson about 16-17 MeV corresponds to a Compton length of 6× 10^-14 m and is by factor 3 longer than the nuclear p-adic length scale L(k=113)∼ 2× 10^-14 m. For k_πW=91 would give h_eff/h= 2^(113-91)/2=2¹¹ to give the nuclear Compton scale. k=115 would give the length scale 4× 10^-14 m not far from 6× 10^-14 m and require h_eff/h= 2^(115-91)/2=2¹². If π_W corresponds to k=89 then h_eff/h= 2^(115-89)/2=2¹³.

   If the π_W Compton scale is scaled from M₉₁ by factor 2^(113-89)/2=2¹² to a Compton length corresponding for ordinary Planck constant to the mass of about m_πW/2¹². This would give m_πW∼ 64 GeV, essentially one half of the mass of the ordinary Higgs about 125.35 GeV and corresponds to the p-adic length scale k=91 just like other weak bosons.

3. Could dark π_W give rise to a dark weak force between electron and nucleus inducing the anomalous isotope shift to electron energies? The increase of the Compton length would suggest the scaling up of the electron nucleus weak interaction geometric cross section by the ratio (m_X/m_W)⁴ ∼ 10²⁰? The weak cross section for dark π_W have the same order of magnitude than nuclear strong interaction cross sections since, apart from numerical factors depending on the incoming four-momenta, the weak cross section for electron-nucleon scattering goes like G_F∼ 1/TeV². This would scale up to 2^113-91=22/TeV²= 4/MeV² (see this). The alternative manner to understand the enhancement could be by assuming that weak bosons are massless below the nuclear scale.
4. Quantum criticality would be essential for the generation of dark phases and long range quantum fluctuations about which the emergence of scaled up dark weak bosons would be an example. Yb is indeed a critical system in the sense that the isotope shift effects are large: this is one reason for why it is so interesting. Why would the quantum criticality of some Yb isotopes induce the generation of dark weak bosons?

It should be noticed that for k=512 assigned with dark M₈₉ hadrons, the scaled down Compton length of dark π_W would be by a factor 8 shorter and correspond to mass 128 MeV not far from the pion mass. What could this mean? Could ordinary pion correspond to a dark dark variant of π_W? This looks strange since usually strong and weak interactions are regarded as completely separate although the CVC and PCAC suggest that they are closely related. In TGD, the notion of induced gauge field implies extremely tight connections between strong and weak interactions.
