eV Scale Sterile Neutrinos in A < inf > 4 < /inf > Symmetric Model

Abstract

The observed anomalies by several short-baseline neutrino oscillation experiments suggest the possible existence of an eV-scale sterile neutrino. Considering a modified discrete A4 flavour symmetric model in the framework of two eV-scale sterile neutrinos, we can explain the current neutrino oscillation parameters along with the neutrinoless double beta decay (NDBD) bound on effective neutrino mass. This model also accommodates a non-zero reactor mixing angle compatible with the current observation.
