abstract
The radiative neutrino mass model with inert doublet dark matter is a promising model for the present experimental issues which cannot be explained within the standard model. We study an extension of this model focusing on cosmological features brought about from the scalar sector. Inflation due to singlet scalars with hierarchical non-minimal couplings with the Ricci scalar may give a favorable solution for both neutrino masses and baryon number asymmetry in the Universe.

A Novel One-loop Model for Majorana Neutrino Mass and Dark Matter
A new model realizes the previously missing T4-3-i one-loop topology for Majorana neutrino mass, predicts one massless neutrino, and offers both fermionic and scalar dark matter candidates.
