In this work, we investigate the two-zero textures of the light neutrino mass matrix within the framework of an asymmetric left-right model. The model is constructed using the modular group \(\varGamma _{3}\) , which is isomorphic to the \(A_{4}\) discrete group, and the light neutrino masses are generated via an extended seesaw mechanism by introducing an additional sterile fermion. After assigning the appropriate \(A_{4}\) charges to the particle content, we identify three classes of two-zero textures. We perform a comprehensive analysis of the phenomenological consequences of these textures.

摘要

In this work, we investigate the two-zero textures of the light neutrino mass matrix within the framework of an asymmetric left-right model. The model is constructed using the modular group \(\varGamma _{3}\) , which is isomorphic to the \(A_{4}\) discrete group, and the light neutrino masses are generated via an extended seesaw mechanism by introducing an additional sterile fermion. After assigning the appropriate \(A_{4}\) charges to the particle content, we identify three classes of two-zero textures. We perform a comprehensive analysis of the phenomenological consequences of these textures.
