N2 - 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 parameter) is used. Consequently the link with the phenomenological energy/mass window is found from the astrophysical and high energy viewpoints. The highest helicity spin-flip cross-sectional values presented in this work coincide with a recent estimation on the axion mass computed in the framework of finite temperature extended lattice QCD and under cosmological considerations.
