A Left-Right Mirror Symmetric Model: Common Origin of Neutrino Mass, Baryon Asymmetry and Dark Matter

TL;DR

This paper proposes a left-right mirror symmetric model that naturally links neutrino mass, baryon asymmetry, and dark matter, providing a unified explanation for these phenomena with testable predictions.

Contribution

It introduces a novel left-right mirror symmetric particle model that connects neutrino mass, baryon asymmetry, and dark matter origins in a unified framework.

Findings

Neutrino mass generated via radiative mechanism.

Baryon asymmetry produced through leptogenesis from mirror charged lepton decay.

KeV-mass sterile Dirac fermion as dark matter candidate.

Abstract

I suggest a left-right mirror symmetric particle model as the natural and aesthetic extension of the SM. As the left-right mirror symmetry breaking, the tiny neutrino mass is generated by the radiative mechanism, the baryon asymmetry through the leptogenesis arises from the characteristic decay of the TeV-scale mirror charged lepton, and a KeV-mass sterile Dirac fermion eventually becomes the CDM. The model can completely account for the common origin of the neutrino mass, the baryon asymmetry and the dark matter, moreover, profoundly uncover the internal connections among them. Finally, I discuss several feasible approaches to test the model predictions and probe the new physics by near future experiments.
