Lepton portal limit of inert Higgs doublet dark matter with radiative neutrino mass
We study an extension of the Inert Higgs Doublet Model (IHDM) by three copies of right handed neutrinos and heavy charged leptons such that both the inert Higgs doublet and the heavy fermions are odd under the Z2 symmetry of the model.The neutrino masses are generated at one loop in the scotogenic fashion.Assuming the neutral scalar of the inert Hi
