On the CP Violation Phase in a Neutrino Mixing Model with an A4 Flavor Symmetry

Phi Quang Van, Nguyen Thi Hong Van

Abstract


Neutrino masses and mixing in an extended standard model acquiring an A4 flavour symmetry are considered. The corresponding three-neutrino mixing matrix obtained via a pertur- bative method allows us to determine the Dirac CP violation phase (\delta_{CP}) as a function of the mixing angles (\theta_{12}, \theta_{23}, \theta_{13}). Then, numerical values and distributions of \delta_{CP} are given. The latter values are quite close to the global fits of the experimental data for both the normal ordering and inverse ordering of the neutrino masses.


Keywords


neutrino mass and mixing, flavor symmetries, models beyond the standard model
