Higgs Inflation and Scalar Dark Matter with Right-handed Neutrinos

TL;DR

This paper explores an extended standard model incorporating right-handed neutrinos and scalar dark matter, analyzing their roles in Higgs inflation and deriving specific mass constraints for dark matter and neutrinos.

Contribution

It introduces a model linking Higgs inflation with scalar dark matter and right-handed neutrinos, providing new mass scale predictions within this framework.

Findings

Dark matter mass around TeV scale

Right-handed neutrino mass near 10^{-14} GeV

Consistent with small tensor-to-scalar ratio

Abstract

We investigate the possibility of Higgs inflation with an extended standard model by right-handed neutrinos and scalar dark matter. We find that the masses of the dark matter and one of the right-handed neutrinos should stand around TeV and $10^{-14}$ GeV scale respectively even if the magnitude of tensor-to-scalar ratio indicates sufficiently small value.
