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 $\mu \rightarrow 3e$ and $\mu \rightarrow e \gamma$ and correlated with neutrino mass within the model.
