Abstract
CP-symmetry violates in oscillations of neutrinos in vacuum in presence of three generations. In this case there is an inherent complex phase in PMNS-matrix. When any two neutrino masses degenerate the CP-violation vanishes. In the present article different mechanisms of CP-symmetry recovery are demonstrated in case of two degenerate neutrino mass-states.

三中微子产生的振荡中的CP振动:简并质量的情况
摘要
CP对称违反了中子在真空中存在三代的振荡。在这种情况下,PMNS矩阵中存在固有的复杂相位。当任何两个中微子质量退化时,CP违反就消失了。在本文中,在两种简并的中微子质量态的情况下,证明了CP对称性恢复的不同机制。
