The remnant CP transformation and its implications

TL;DR

This paper explores the implications of remnant CP transformations, focusing on a generalized mu-tau reflection symmetry and its impact on neutrino CP phases and mixing angles relevant for neutrino experiments.

Contribution

It introduces a generalized mu-tau reflection symmetry within remnant CP transformations, linking Majorana phases to CP parities and correlating the Dirac CP phase with atmospheric mixing angle.

Findings

Majorana phases have CP conserving values

Dirac CP phase correlates with atmospheric mixing angle

Implications for neutrino oscillation experiments

Abstract

In the context of remnant CP transformations, I briefly discuss a generalized $\mu-\tau$ reflection symmetry, where the "Majorana" phases have CP conserving values, which are directly related with the CP parities of neutrino states. Also, one finds that the "Dirac-like" CP violation phase is correlated with the atmospheric mixing angle, giving important phenomenological implications for current and future long baseline oscillation neutrino experiments.
