A model for cobimaximal neutrino mixing
June 26, 2022
Here we explore a flavor model to understand the cobimaximal lepton mixing ansatz based on $A_4$ non-Abelain discrete symmetry. Guided by the symmetry, we explicitly construct the relevant lepton mass matrices with the involvement of $A_4$ flavons. Tiny neutrino mass and mixing are analyzed here relying on the type-I seesaw mechanism
and we study the associated phenomenology. Subsequently, we draw interesting correlations between the neutrino mixing angles and absolute neutrino masses.
