Testability of the Higgs inflation scenario in a radiative seesaw model

TL;DR

This paper explores the viability of Higgs-driven inflation within a radiative seesaw model, showing some parameter regions are compatible with current experimental data and could be tested at future colliders.

Contribution

It demonstrates that Higgs inflation can occur in a radiative seesaw model and identifies parameter regions consistent with existing experimental constraints.

Findings

Certain scalar field parameters align with LHC, neutrino, and dark matter data.

The model's predictions can be partially tested at the International Linear Collider.

Abstract

The Higgs inflation scenario is an approach to realize the inflation, in which the Higgs boson plays a role of the inflaton without introducing a new particle. We investigate a Higgs inflation scenario in the so-called radiative seesaw model proposed by E. Ma. We find that a part of parameter regions where additional scalar fields can play a role of an inflaton is compatible with the current LHC results, the current data from neutrino experiments and those of the dark matter abundance as well as the direct search. We show that we can partially test this model by measuring masses of scalar bosons at the International Linear Collider.
