Antimatter as Dark Matter?

In CERN (see this), physicists have made measurements of how matter atoms and, for the first time antmatter atoms, absorb light, and found no differences in the energies of their excited states.

This is predicted by CPT symmetry. Notice however that CP and T can be separately broken and that this is indeed the case. Kaon is classical example of this in particle physics. Neutral kaon and antikaon behave slightly differetly.

This finding forces to repeat an old question. Where does the antimatter reside? Or does it exist at all?

GUTs predicted that baryon and lepton number are not conserved separately and suggested a solution to the empirical absence of antimatter. GUTs have been however dead for years and there is actually no proposal for the solution of
matter-antimatter asymmetry in the framework of mainstream theories (actually there are no mainstream theories after the death of superstring theories which also assumed GUTs as low energy limits!).

In TGD framework many-sheeted space-time suggests posible solution to the problem. Matter and antimatter are at different space-time sheets. One possibility is that antimatter corresponds to dark matter in TGD sense that is a phase with h_eff=n× h, n=1,2,3,… such that the value of n for antimatter is different from that for visible matter. Matter and antimatter would not have direct interactions and would interact only via classical fields or by emission of say photons by matter (antimatter) suffering a phase transition changing the value of h_effbefore absorbtion by antimatter (matter). This could be rather rare process. Biophotons could be produced from dark photons by this process and this is assumed in TGD based model of living matter.

What the value of n for ordinary visible matter could be? The naive guess is that it is n=1, the smallest possible value. Randell Mills has however claimed the existence of scaled down hydrogen atoms – Mills calls them hydrinos – with ground state binding energy considerably higher than for hydrogen atom. The experimental support for the claim is published in respected journals and the company of Mills is developing a new energy technology based on the energy liberated in the transition to hydrino state.

These findings can be understood in TGD framework if one has actually n=6 for visible atoms and n=1, 2, or 3 for hydrinos. Hydrino states would be stabilized in the presence of some catalysts. See this.

This also suggest a universal catalyst action. Among other things catalyst action requires that reacting molecule gets energy to overcome the potential barrier making reaction very slow. If an atom – say hydrogen – in catalyst suffers a phase transition to hydrogen like state, it liberates binding energy, and if one of the reactant molecules receives it it can overcome the barrier. After the reaction the energy can be sent back and catalyst hydrino returns to the ordinar hydrogen state.

So: could it be that f one has n=6 for stable matter and n is different from this for stable antimatter? Could the small CP breaking cause this?
