Abstract

Motivated by recent results from neutrino experiments, we study the neutrino masses and mixing in the framework of a SUSY SU(5)×A4SU(5)\times \mathbb{A}_{4} model. The hybrid of Type I and Type II seesaw mechanisms leads to the nonzero value of the reactor angle θ130\theta_{13}\neq 0 and to the recently disfavored maximal atmospheric angle θ2345\theta_{23} \neq45^{\circ} by the NOvA experiment. The phenomenological consequences of the model are studied for both normal and inverted mass hierarchies. The obtained ranges for the effective Majorana neutrino mass mββm_{\beta \beta}, the electron neutrino mass mνem_{\nu_{e}}, and the CPCP violating phase δCP\delta_{CP} lie within the current experimental allowed ranges where we find that the normal mass hierarchy is favored over the inverted one.
