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 $f_a$ (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.

从新获得的中微子螺旋自旋翻转的横截面 $F（\mathrm{[R}，Ť）$从现象学上分析了具有动态扭转场的引力模型。为此，由于横截面的对数能量依赖性，与轴衰变常数的关系$F_{\mathrm{一种}}$（Peccei–Quinn参数）被使用。因此，从天体物理学和高能观点来看，发现了与现象学能量/质量窗口的联系。在这项工作中提出的最高螺旋自旋翻转横截面值与最近对有限温度扩展晶格QCD框架中以及在宇宙学考虑下计算的轴突质量的估计相吻合。
