Deviation from Tribimaximal mixing using A4 flavour model with five extra scalars

A neutrino mass model with five extra scalars is constructed using A4×Z3×Z2 discrete symmetry group. The resultant mass matrix is able to give necessary deviation from Tribimaximal mixing which reproduces the current neutrino masses and mixing data with good accuracy. The model gives testable predic...

Zusammenfassung:A neutrino mass model with five extra scalars is constructed using A4×Z3×Z2 discrete symmetry group. The resultant mass matrix is able to give necessary deviation from Tribimaximal mixing which reproduces the current neutrino masses and mixing data with good accuracy. The model gives testable prediction for the future measurements of the neutrinoless double-beta decay parameter |mββ|. The analysis is consistent with latest cosmological bound Σmi≤0.12 eV.
