A TeV-scale model for neutrino mass, DM and baryon asymmetry

TL;DR

This paper proposes a TeV-scale model that simultaneously explains neutrino oscillations, dark matter stability, and baryon asymmetry through a three-loop neutrino mass mechanism, an extra Higgs doublet, and specific phenomenological predictions.

Contribution

It introduces a novel TeV-scale model integrating neutrino mass generation, dark matter stability, and baryogenesis with distinctive charged Higgs phenomenology.

Findings

Neutrino masses generated at three-loop level.

Dark matter stability guaranteed by exact Z2 symmetry.

Model predicts unique charged Higgs signatures.

Abstract

We discuss a model which would explain neutrino oscillation, dark matter, and baryon asymmetry of the Universe simultaneously by the physics at TeV scales. 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 also guaranteed. The extra Higgs doublet is required not only for the tiny neutrino masses but also for successful electroweak baryogenesis. The model provides various discriminative predictions especially in charged Higgs phenomenology.
