Dark matter candidates, helicity effects and new affine gravity with torsion

The cross section for neutrino helicity spin-flip obtained from a new f(R,T) model of gravitation with dynamic torsion field is phenomenologically analyzed. To this end, due to the logarithmical energy dependence of the cross section, the relation with the axion decay constant fa (Peccei–Quinn param...
