Two Loop Neutrino Model with Dark Matter and Leptogenesis

TL;DR

This paper presents a two-loop neutrino mass model at TeV scale that incorporates dark matter candidates and resonant leptogenesis, analyzing their compatibility with experimental constraints and potential distinguishability.

Contribution

It introduces a novel two-loop radiative neutrino model with dual dark matter candidates and explores its implications for leptogenesis and experimental detection.

Findings

Dark matter candidates can satisfy relic density and direct detection bounds.

Resonant leptogenesis at TeV scale can be distinguished from other scenarios.

Model provides a unified framework linking neutrino mass, dark matter, and leptogenesis.

Abstract

We study a two-loop induced radiative neutrino model at TeV scale with global $U(1)$ symmetry, in which we analyze dark matter and resonant leptogenesis. The model includes two kinds of dark matter candidates. We discuss what kind of dark matter can satisfy the observed relic density as well as the current direct detection bound, and be simultaneously compatible with the leptogenesis. We also discuss whether our resonant leptogenesis can be differentiated from the other scenarios at TeV scale or not.
