Dark matter stability from non-Abelian discrete flavor symmetries

Abstract

We present a mechanism for the dark matter stability in the framework of a non-Abelian avour symmetry renormalizable model. The same non-abelian discrete avor symmetry which accounts for the observed pattern of neutrino oscillations, spontaneously breaks to a Z2 subgroup which renders DM stable. The simplest scheme leads to a scalar doublet DM potentially detectable in nuclear recoil experiments, inverse neutrino mass hierarchy, hence a neutrinoless double beta decay rate accessible to upcoming searches.
