The story about tetraquark, which measurably existed at two places simultaneously

There has been strange post rotating in the web. It claims that a tetraquark with very strange properties has been discovered in CERN. Very probably, this is only one example of the nonsense filling the web nowadays and belongs to the same category as the many miracles related to 3I/ATLAS.

The post makes the weird claim that the LHC tetraquark has been detected at two places simultaneously at a distance of 1.4 meters. This is claimed to demonstrate that quantum coherence in this scale is involved. Standard quantum mechanics however says that the position measurement localizes the particle so that this is not possible. The post claims that the source is CERN Large Hadron Collider, Physical Review Letters 2025. There is no such report. Physical Review Letters. Tetraquark has been discovered but everything seems to be business as usual. There is however a strange co-incidence related to the TGD view of quantum physics, predicting the possibility of quantum coherence in arbitrarily long length scales and this motivated the writing of this post.

Just for fun, suppose there indeed is evidence that a tetraquark with a lifetime of about τ=about 10^-23 seconds was detected at a distance of L=1.4 m.

1. This is impossible since the maximal distance that tetra quark can travel is about d= c×τ= 3×10^-15 meters, which corresponds to the length scale of proton. The ratio L/d= 1.4×10¹⁵/3 so that tetraquark should survive for time t= L/c= .5×10^-8 s.
2. Could time dilation explain this? The lifetime of tetraquark is τ in the rest system. The lifetime T detected in the lab is longer than τ by dilation factor gamma= 1/(1-v²/c²)^1/2 giving γ= T T/τ= L/d∼ 3×10^-15, of order about 10¹⁵×m_T, where m_T is tetraquark mass of order proton mass. The energy of the tetraquark should be about 10¹² times the proton mass. The energy of protons in the cm system (lab) is a few hundred proton masses. Clearly, this option makes no sense.
3. What about TGD? TGD predicts a hierarchy of effective Planck constants h_eff and the lifetime for a particle with h_eff is scaled up by h_eff/h and for large values of h_eff the particle can be very long. And now comes the motivation for this post: the gravitational Planck constant is h_gr/h ∼ 10¹⁴ assignable to Earth particle pair and playing key role in TGD inspired quantum biology, corresponds to the ratio L/d. If the finding were true it would mean a direct and very dramatic support for the basic prediction of TGD. Knowing that the web is totally corrupted by fake news after the removal of fact checking, I do not take this possibility seriously.
