Abstract

We consider the scotogenic model involving an extra inert scalar doublet and three SM-singlet fermions, all under an additional Z2 symmetry, to explain inflation, dark matter, baryogenesis and neutrino masses simultaneously. The inert scalar doublet is coupled to gravity non-minimally and after a conformal transformation forms the inflation in the early Universe.Later its lightest scalar component freezes-out to give the dark matter candidate. Baryogenesis happens via leptogenesis by the decay of N1 to SM leptons and the inert doublet particles. The Ni ’s and the inert doublet combine with the SM neutrinos and the Higgs vacuum expectation value (vev) to generate neutrino masses at the loop level. We show that with the scotogenic model, we get a very economical model for combining inflation with dark matter, baryogenesis and neutrino masses.
