摘要

摘要我们研究了中微子在双味模型中与物质和电磁场的同时相互作用。我们证明，在通过带电电流相互作用的情况下，不仅自旋翻转转换的概率中会出现违反（T\）不变性的项（invariance violating terms），而且具有相同螺旋度的状态之间的味道转换概率中也会出现违反（T\）不变性的项（invariance violating terms）。

Violation of the $$T$$ invariance in the probabilities of spin–flavor transitions of neutrino characterized by a real mixing matrix

Abstract

We study the simultaneous interaction of a neutrino with matter and the electromagnetic field in the two-flavor model. We show that $T$-invariance violating terms can appear in the probabilities of not only spin-flip transitions but also flavor transitions between states with the same helicity in the case of the interaction via charged currents.
