Inflation in a modified radiative seesaw model

Understand

The existence of the inflationary era in the early Universe seems to be strongly supported by recent CMB observations.

• However, only a few realistic inflation scenarios which have close relation to particle physics seem to have been known unfortunately.
• 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.
• In order to make the model include inflation, we extend it by a complex scalar field with a specific potential.
