CP Violation in Two Zero Texture Neutrino Mass Matrices

TL;DR

This paper discusses how certain neutrino mass matrices with two texture zeros inherently predict CP violation and non-zero 1-3 mixing angles, with a specific exception under maximal mixing conditions.

Contribution

It demonstrates that two-zero texture neutrino mass matrices generally imply CP violation and non-zero 1-3 mixing, clarifying conditions under which CP violation may not occur.

Findings

Two-zero texture neutrino mass matrices predict CP violation.

Such matrices generally imply non-zero 1-3 mixing.

An exception exists in class C with maximal mixing.

Abstract

It has been shown that the neutrino mass matrices with two texture zeros in the charged lepton basis predict non-zero 1-3 mixing and are necessarily CP violating with one possible exception in class C for maximal mixing.
