ILC phenomenology in a TeV scale radiative seesaw model for neutrino mass, dark matter and baryon asymmetry

TL;DR

This paper introduces a TeV-scale radiative seesaw model that explains neutrino masses, dark matter, and baryon asymmetry through extended Higgs sector dynamics and right-handed neutrinos, with testable predictions at colliders.

Contribution

It presents a novel TeV-scale model that simultaneously addresses neutrino mass, dark matter stability, and baryon asymmetry with distinctive collider signatures.

Findings

Neutrino masses generated at three-loop level due to $Z_2$ symmetry.

Model predicts specific Higgs phenomenology testable at LHC and ILC.

Dark matter candidate stability guaranteed by symmetry.

Abstract

We discuss phenomenology in a new TeV scale model which would explain neutrino oscillation, dark matter, and baryon asymmetry of the Universe simultaneously by the dynamics of the extended Higgs sector and TeV-scale right-handed neutrinos. Tiny neutrino masses are generated at the three-loop level due to the exact $Z_2$ symmetry, by which the stability of the dark matter candidate is guaranteed. The model provides various discriminative predictions in Higgs phenomenology, which can be tested at the Large Hadron Collider and the International Linear Collider.
