Portal Dark Matter in the Minimal Model

Table 2

The particle content of the minimal extended SM with symmetry. In addition to the SM particle content (, , ), the three right-handed neutrinos [ (, ) and ] and the Higgs field () are introduced. Because of the parity assignment shown here, is a unique (cold) dark matter candidate.
