Radiative Neutrino Mass, Dark Matter and Leptogenesis

TL;DR

This paper introduces an extended standard model where neutrinos are Dirac particles with masses generated radiatively, and the new fields also explain dark matter and matter-antimatter asymmetry.

Contribution

It presents a novel model linking neutrino mass, dark matter, and leptogenesis through new fields and one-loop radiative mechanisms.

Findings

Neutrino masses arise from one-loop radiative processes.

The model accounts for dark matter and baryon asymmetry.

Unified explanation for neutrino mass, dark matter, and leptogenesis.

Abstract

We propose an extension of the standard model, in which neutrinos are Dirac particles and their tiny masses originate from a one-loop radiative diagram. The new fields required by the neutrino mass-generation also accommodate the explanation for the matter-antimatter asymmetry and dark matter in the universe.
