Study of Neutrino Mass Matrix with One Vanishing Subtrace using Trimaximal Mixing

Abstract

In this work we study the phenomenological implications of neutrino mass matrix with one vanishing subtrace using trimaximal mixing matrix, TM 1. Here, we have analysed only two patterns of one vanishing subtrace i.e., S 11 = 0 and S 12 = 0. We find that the two considered patterns accommodate the present neutrino oscillation data for both Normal Hierarchy and Inverted Hierarchy. For both the patterns, we present the correlation plots of the neutrino oscillation parameters and calculate the effective Majorana mass, hence study the neutrinoless double beta decay rate.
