Description
There are several extension of the standard model predicting good dark matter candidates like in supersymmetry. However, it turns out that in most models the stability of the dark matter is assumed by hand, typically assuming a parity symmetry. Of course any of these models may be correct, but certainly it would be desirable to provide a fundamental explanation of the origin of the stability
of the dark matter. The stabilization mechanism can give constraints on the structure of the model and therefore on the associated phenomenology. We propose a model where the stability is garantee by a residual Z2 symmetry arising from the spontaneous breaking of the flavor non-abelian discrete symmetry. We give two example based on A4 and D4.
