Extension of a radiative neutrino mass model based on a cosmological view point

TL;DR

This paper extends a radiative neutrino mass model to incorporate cosmic inflation, simultaneously explaining baryon asymmetry and dark matter, linking neutrino physics with cosmological phenomena.

Contribution

It introduces a model connecting neutrino mass generation with inflation, baryon asymmetry, and dark matter within a unified framework.

Findings

Provides a consistent explanation for inflation, baryon asymmetry, and dark matter.

Links scalar couplings in neutrino mass models to inflation parameters.

Suggests a unified approach to particle physics and cosmology.

Abstract

We consider an extension of the radiative neutrino mass model at TeV regions so as to give the origin for inflation of the universe. This extension also gives a consistent explanation for both the origin of baryon number asymmetry and dark matter. A small scalar coupling which plays a crucial role in the neutrino mass generation in the original model may be related to parameters which are control inflation.
