Dark matter, neutrino masses, and high scale validity of an inert Higgs doublet model
We consider a two-Higgs doublet scenario containing three $SU(2{)}_{L}$ singlet heavy neutrinos with Majorana masses. The second scalar doublet as well as the neutrinos are odd under a ${Z}_{2}$ symmetry. This scenario not only generates Majorana masses for the light neutrinos radiatively but also makes the lighter of the neutral …
