Two-loop radiative seesaw mechanism with multicomponent dark matter explaining the possible γ excess in the Higgs boson decay and at the Fermi LAT

A nonsupersymmetric model of a two-loop radiative seesaw is proposed. The model contains, in addition to the standard model Higgs boson, an inert SU(2) sub(L) doublet scalar [eta] and two inert singlet scalars [varphi] and chi . The lepton number is softly broken by a dimension-two operator, and the...
