Neutrino Model in Left-Right Symmetric Linear Seesaw Augmented with $A_4$ Modular Group
Abstract
In this work, we have implemented modular symmetry in the left-right symmetric linear seesaw model. Interestingly, such modular symmetry restricts the proliferation of flavon fields, and as a result, the predictibility of the model is enhanced. The fermion sector of the model comprises of quarks, leptons and a sterile fermion in each generation, while the scalar sector consists of Higgs doublets and bidoublets. We investigate numerically various Yukawa coupling co-efficients, the neutrino masses and mixing parameters in our intended model and predictions become consistent with range of current neutrino oscillation data. We also studied the non-unitarity, effects on lepton flavor violation in our model and evolution of lepton asymmetry to explain the current baryon asymmetry of the universe.
