Systematic investigation of minimal Scotogenic models

We carry out a systematic investigation for minimal Scotogenic models based on a dark U(1)_D gauge symmetry, in which the neutrino masses are induced at the one-loop level and include a chiral dark matter (DM) candidate. Moreover, we assume this U(1)_D gauge symmetry is broken by only one Higgs singlet scalar that also generates masses to all dark fermions. The stability of the DM candidate is ensured by a residual symmetry of U(1)_D gauge symmetry. Furthermore, we also explore the associated DM phenomenology of one of the minimal models.
