The dark matter particle detected by LUX-ZEPLIN detector is identifiable as dark pion of M89 hadron physics predicted by TGD!

I just learned of a direct detection of dark matter. The news was published already towards the end of 2025 (see this. I glue part of the news here.

The LUX-ZEPLIN detector (see this) at the Sanford Underground Research Facility, located 1,500 meters beneath the former Homestake Gold Mine, recorded 8 candidate dark matter interaction events over 1,000 days of operation that carry statistical certainty of 5.2 sigma crossing the discovery threshold physicists require for particle physics announcements. The detector uses 10 tonnes of ultra-pure liquid xenon cooled to minus 108 degrees Celsius, surrounded by water tanks shielding against cosmic rays that would overwhelm the faint dark matter signal at shallower depths.

Dark matter particles theorized as Weakly Interacting Massive Particles with masses between 10 and 1,000 times the proton mass produce tiny flashes of scintillation light and ionization when they collide with xenon nuclei, distinguishable from radioactive background through their characteristic dual-signal fingerprint.

The detected events carry particle masses consistent with a 65 proton-mass dark matter candidate, within the theoretical range predicted by supersymmetric extensions of the standard model. Independent verification is already underway at the PandaX-4T detector in China and the XENONnT detector in Italy's Gran Sasso Laboratory, with results expected within six months.

What does TGD say about the claimed 5.2 sigma discovery?

1. One of the most dramatic predictions of TGD is a scale hierarchy of standard model physics labelled by Mersenne primes and their Gaussian counterparts. This hierarchy would correspond to the hierarchy of color partial waves associated with the Dirac equation in H= M⁴× CP₂ in which space-times are 4-surfaces obeying a slightly non-deterministic holography. The failure of strict classical determinism of the holography at the level of space-time surfaces, forcing what I call zero energy ontology (ZEO), is crucial for both the non-triviality of quantum TGD and for TGD inspired theory of consciousness.

   The mass scales of leptons and hadrons of a standard model physics associated with a given pair of quark-like and leptonic color partial wave multiplets is conjecture to be proportional to the inverse of the square root of the Mersenne or Gaussian Mersenne characterizing the scaled copy: for the most recent articles about p-adic thermodynamics, replacing Higgs mechanism (see this and this). For instance, for electron one would correspond to Mersenne prime M₁₂₇ =2¹²⁷-1.

2. Ordinary hadrons would correspond to Mersenne prime M₁₀₇= 2¹⁰⁷-1. The Mersenne prime M₈₉ would correspond to a mass scale, which is 512 times the mass scale of ordinary hadron physics. During about 2 decades pieces of evidence for M₈₉ hadron physics at LHC have been accumulating (see for instance this, this and this). M₈₉ hadron physics would dramatically modify the model for the energy production in the Sun (see this).
3. TGD predicts a hierarchy of effective Planck constants h_eff coming as integer multiples of its minimal value, which considerably smaller than ordinary Planck constant. The phases with non-standard value of Planck constant would behave like dark matter since vertices involving fermions with particles having different values of h_eff are not possible. The 2-vertex changing the value of h_eff is however possible and phase transitions changing h_eff are possible.
4. A TGD based explanation for the LUX-ZEPLIN events interpreted in terms of dark matter would be as a pion of M₈₉ hadron physics identifiable as a scaled up copy of ordinary M₁₀₇ hadron with a mass scale which is 512 times higher but having a non-standard value of effective Planck constant so that the M₈₉ hadrons would be like dark matter. The scaling of the mass .134 MeV of the ordinary pion by factor 512 gives mass of 67 GeV. This is exactly the reported mass if proton mass 940 MeV is approximated as 1 GeV (the error is 6 per cent)!

   M₈₉ hadrons would be created as a phase of ordinary matter with scaled up valued of effective Planck constant guaranteeing that at quantum criticality for the phase transition the Compton lengths of M₈₉ hadrons, scaled by factor h_eff/h are same as for ordinary hadrons. This requires that the ratio of h_eff/h equals to the ratio p-adic length scales associated with M₁₀₇ and M₈₉ equal to 2^(107-89)/2= 2⁹=512.
