Abstract :
[en] Extending the standard model with three right-handed neutrinos (Nk) and a second Higgs doublet (η), odd under the discrete parity symmetry Z2, Majorana neutrino masses can be generated at one-loop order. In the resulting model, the lightest stable particle, either a boson or a fermion, might be a dark matter candidate. Here we assume a specific mass spectrum (M1≪M2

If the sterile neutrinos as WDM are generated in decays of some heavier particles, then the situation may change.
