Neutrinoless double-beta decay and lepton flavor violation in discrete flavor symmetric left-right symmetric model

Abstract

In this work, we have studied neutrino less double beta decay(NDBD) and charged lepton flavor violation(CLFV) in a generic Left-Right symmetric model (LRSM). In this framework, type-I and type-II seesaw terms arise naturally. We have used $A_4\times Z_2$ discrete flavor symmetry to realize the LRSM. Within the model, we have considered type-I and type-II dominant cases and analyzed the new physics contributions to the NDBD process coming from different particles of LRSM. We tried to find the leading order contributions to NDBD in type-I and type-II seesaw along with the decay rate of the process in our work. We have also studied different charged lepton flavor violating processes such as $\mu \to 3e$ and $\mu \to e\gamma$ and correlated with neutrino mass within the model.
