Abstract

We propose a flavor symmetric approach to unify the origin of dark matter (DM) with the nonzero θ13 in the lepton sector. In this framework, the breaking of a U(1) flavor symmetry to a remnant Z2 ensures the stability of the DM and gives rise to a modification to the existing A4-based tribimaximal neutrino mixing to attain the required nonzero values of sinθ13. 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.
