Unifying the flavor origin of dark matter with leptonic nonzero ${\theta }_{13}$

Abstract

We propose a flavor symmetric approach to unify the origin of dark matter (DM) with the non-zero ${\theta }_{13}$ in the lepton sector. In this framework, breaking of a $U(1)$ flavor symmetry to a remnant $Z_2$ ensures the stability of the DM and gives rise to a modification to the existing $A_4$-based tri-bimaximal neutrino mixing to attain the required non-zero $\sin {\theta }_{13}$. This results in a range of Higgs portal coupling of the DM which can be potentially accessible at various ongoing and future direct and collider search experiments.
