Majorana Dark Matter and Neutrino Mass in a Singlet-Doublet Extension of the Standard Model

Dark Matter Investigation Using Double Beta Decay Experiments

“…Neutrinoless double beta decay is an important test for Physics beyond the Standard Model; the investigation of this process allows for studying the possible Majorana nature of the neutrino and the possible violation of the Leptonic quantum number [1,2]. In particular, the Seesaw models provide a mechanism to generate small neutrino masses (see, e.g., [3]); moreover, both the problem of baryogenesis [4] and some Dark Matter (DM) candidates [5][6][7] can be addressed.…”
