Texture zero neutrino mass matrix in left-right symmetric model: a phenomenological study

Abstract

Texture zeros play a decisive role in the neutrino phenomenological study as well as in reducing the number of free parameters and correlating them in the beyond Standard Model framework. In this work we study the possibility concerning the origin of texture zero in the neutrino mass matrix in the context of the left-right symmetric model (LRSM). Texture zeros in the light neutrino mass matrix bring about the persistence of allowed and disallowed classes of texture zero classification. In this work we study the lepton number-violating neutrinoless double beta decay (NDBD) corresponding to standard light neutrino, heavy right-handed neutrino and scalar triplet contributions in LRSM. We have also tried to study charged lepton flavor violation (CLFV) within this framework and see if we can simultaneously study these observables within a common parameter space in the model. The study has been carried out for both normal and inverted mass orderings which interestingly rules out certain textures while considering the said observables.
