Phenomenology of Trimaximal mixing with one texture equality

High Energy Physics - Phenomenology 2022-10-07 v2

Abstract

We study neutrino mass matrices with one texture equality and the neutrino mixing matrix having either its first (TM1_1) or second (TM2_2) column identical to that of the tribimaximal mixing matrix. We found that out of total fifteen possible neutrino mass matrices with one texture equality, only seven textures are compatible with TM1TM_1 mixing and six textures are compatible with TM2TM_2 mixing in the light of the current neutrino oscillation data. These textures have interesting implications for the presently unknown parameters such as the neutrino mass scale, effective Majorana neutrino mass, the atmospheric mixing and the Dirac- and Majorana-type CP violating phases. We, also, present the S3S_{3} group motivation for some of these textures.
