More evidence for dark matter-like particles in Milky Way: TGD view of color as an explanation?

Sabine Hossenfelder told about quite recent finding possibly related to dark matter (see this). “Anomalous ionization in the central molecular zone by sub-GeV dark matter” can be found in arXiv (see this). Here is the abstract of the article:

We demonstrate that the anomalous ionization rate observed in the Central Molecular Zone can be attributed to MeV dark matter annihilations into e⁺e^- pairs for galactic dark matter profiles with slopes γ> 1. The low annihilation cross-sections required avoid cosmological constraints and imply no detectable inverse Compton, bremsstrahlung or synchrotron emissions in radio, X and gamma rays. The possible connection to the source of the unexplained 511 keV line emission in the Galactic Center suggests that both observations could be correlated and have a common origin.

I will try to summarize what I understood from Sabine’s Youtube talk.

1. It has been observed that from the Central Molecular Zone, where stars are formed, arrives more IR light than expected. Hydrogen forms normally H₂ molecules and they cannot explain the IR light in terms of vibrational excitations. H₃⁺ could give rise to the infrared light.
2. There should be a mechanism leading to the formation of ionized H₃ molecules. Electrons could cause the ionization and the proposal is that dark particles in MeV mass range could serve as the source of the ionizing electrons. The proposal is that two dark particles in this energy range annihilate to electron-positron pairs and the electrons ionize the H₃ molecules.
3. There indeed exists earlier evidence for gamma rays with energy 511 eV from the Milky Way center (see this and this). They could be generated in the annihilation of dark particles with mass slightly above MeV to gamma pairs. This would happen in the collisions of these particles and this would require that the dark particles are very nearly at rest.

TGD leads to a much simpler explanation for the findings in terms of particles, whose mass .511 MeV is only slightly above the mass of electron (see this). They would directly decay to electron positron pairs.

1. The empirical findings motivating this hypothesis emerged already in the seventies from the finding that in heavy ion collisions with collision energy near the criticality to overcome Coulomb wall, anomalous electron-positron pairs were observed with energy, which was slightly more than twice the rest mass .5 MeV of electrons. In the standard model, the decay widths of weak bosons do not allow new particles in this mass range and this was probably the reason why the findings were forgotten.
2. An essential role in the explanation is played by the TGD view of color symmetry and dynamics of strong interactions, which both are in some respects very different from the QCD view. I have described this view in (see this) inspired by the quite recent finding of large isospin breaking in the production of kaon pairs. The production rate for charged kaons is 18.4 per cent higher than for neutral kaons challenging QCD. The explanation that comes to mind is that color gauge coupling slightly depends on the electric charge of the quark besides the weak dependence on the p-adic mass scale of the quark (now u or d quark).

How does the TGD based view of color lead to this proposal?

1. Color corresponds to color partial waves in CP₂ and a spectrum of colored spinor harmonics in H=M⁴× CP₂ are predicted for both quarks and leptons in CP₂. The color partial waves correlate with electroweak quantum numbers unlike the observed color quantum numbers. This means large isospin breaking (see this) at the fundamental level, where all classical gauge fields and gravitational field are expressible in terms of H coordinates and their gradients and only four of them is needed by general coordinate invariance. One can imagine a mechanism, which guarantees weak screening in scales longer than weak boson Compton length and this mechanism also explains the color quantum numbers of physical leptons and quarks.

The weak screening above weak scale could take place by a pair of left and right-handed neutrinos assignable to the monopole flux tubes associated with the quark and it would also give the needed additional color charge so that quarks would be color triplets and leptons color singlets.

It is however possible to also have color octet and higher triality t=0 excitations of leptons and analogous excitations of quarks (see this). The particles with mass slightly above 2m_e would be analogs of pions, electropions as I have called them. Also muopions and taupions are predicted and there are experimental indications also for them (see this, this, and this) but forgotten since they cannot exist in the standard model. How to understand the darkness of electropions?

1. The darkness of the leptopions and possible other leptomesons could make it possible to avoid the problems with the decay widths of weak bosons. But what could this darkness mean? The experiments of Blackman and others (see this) suggest that the irradiation of the brain with EEG frequencies has behavioral and physiological effects and that these effects are quantal and correspond to cyclotron transitions in a magnetic field of about 2B_E/5, where B_E is the Earth’s magnetic field. This does not make sense in standard quantum theory since the value of the Planck constant is more than 10 orders of magnitude too small and the cyclotron energy would be much below the thermal energy. I have proposed that the Planck constant, or effective Planck constant h_eff, has a spectrum and its value can be arbitrarily large.

In the recent formulation of TGD involving number theoretic vision h_eff hierarchy follows as a prediction. The large value of h_eff would give rise to quantum coherent phases of the ordinary matter at magnetic/field body of the system and these phases would behave like dark matter in the sense that only particles with the same value of h_eff can appear in the vertices of TGD analogs of Feynman diagrams.

The natural guess is that the 511 keV particle is dark in this number theoretic sense. It would not be created in the decays of ordinary weak bosons unless they themselves are dark with the same value of h_eff. The second option is that leptomesons can appear only in the dark phase at quantum criticality associated with the situation in which the Coulomb wall can be overcome. Dark phases in this sense appear only at quantum criticality making possible long range quantum fluctuations and quantum coherence.

For along time I thought that the darkness in number theoretic sense could correspond to the darkness of the galactic dark matter but now it seems that this is be the case (see this, this and this). Classically, galactic dark matter could correspond to Kähler magnetic and volume energy of cosmic strings, which are 4-surfaces in M⁴× CP₂ with 2-D M⁴ projection. One can of course ask, whether the quantum classical correspondence implies that classical energy equals to its fermionic counterpart in which case these view of dar matter could be equivalent.

The number theoretic darkness would however make itself visible also in cosmology. The transformation of ordinary particles to dark phases at the magnetic bodies, forced by the unavoidable increase of number theoretical complexity implying evolution, would reduce the amount of ordinary matter and this could explain why baryonic (and also leptonic) matter seems to gradually disappear during the cosmic evolution. To sum up, the recently observed isospin anomaly of strong interactions together with additional empirical support for the TGD view of color is rather encouraging. This hypothesis is testable without expensive accelerators already now. Only the readiness to challenge the belief that QCD is the final theory of strong interactions would be required and I am afraid that it takes time to reach this readiness. Two very different views of science are competing. The old fashioned science in which anomalies were Gold nuggets and the Big Science in which everything is understood if 98 percent is understood.

See for instance the chapter Recent Status of Lepto-Hadron Hypothesis.
