Description

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. Assuming this $U(1{)}_D$ gauge symmetry is broken by only one Higgs singlet scalar that also generates masses to all dark fermions, we analyze the stability of the DM candidate which is ensured by a residual symmetry of U(1)_D gauge symmetry.
There can be different DM scenarios explored in this framework and we investigate the associated scalar and fermonic DM phenomenology of one of the minimal models.
