Abstract: (IOP)
We consider the radiative generation of neutrino mass through the interactions of neutrinos with MeV dark matter. We construct a realistic renormalizable model with one scalar doublet (in additional to the standard model doublet) and one complex singlet together with three light singlet Majorana fermions, all transforming under a dark U(1)D symmetry which breaks softly to Z(2). We study in detail the scalar sector which supports this specific scenario and its rich phenomenology.Note:
