【 摘 要 】

The existence of non-baryonic Dark Matter is well established by cosmological and astrophysical probes, however its detailed nature still remains elusive. Among the extensions of the Standard Model (SM) explaining the DM relic abundance, the simplest one is the inert dark matter, where a scalar field is added to the Standard Model which is stabilized by a Z2 symmetry. We intend to give a brief review of this scenario and its possible connection with neutrino physics. In particular the discrete dark matter mechanism will be outlined. This mechanism consists in an extended SM with a non-Abelian flavor symmetry. When the flavor symmetry is spontaneously broken by the electroweak symmetry breaking mechanism, it explains the neutrino mixing patterns and at the same time renders the dark matter stable.
