Modified TBM and role of a hidden ${\mathbb{Z}}_2$

Abstract

In a residual ${\mathbb{Z}}_2\times {\mathbb{Z}}_2$ symmetry approach, we investigate minimally perturbed Majorana neutrino mass matrices. Constraint relations among the low energy neutrino parameters are obtained. Baryogenesis is realized through flavored leptogenesis mechanism with quasi-degenerate right handed (RH) heavy neutrinos.
