Baryogenesis and Asymmetric Dark Matter from The Left-Right Mirror Symmetric Model

TL;DR

This paper proposes a left-right mirror symmetric model that explains the origins of baryon asymmetry and dark matter, linking them naturally and predicting testable consequences like specific dark matter neutrino mass.

Contribution

It introduces a novel symmetric model that simultaneously accounts for standard model phenomena, matter-antimatter asymmetry, and dark matter with testable predictions.

Findings

The model naturally explains baryon and dark matter asymmetries.

Predicts dark matter neutrino mass to be 3.1 times the proton mass.

Feasible for experimental testing in future experiments.

Abstract

The paper suggests a left-right mirror symmetric model to account for the baryogenesis and asymmetric dark matter. The model can simultaneously accommodate the standard model, neutrino physics, matter-antimatter asymmetry and dark matter. In particular, it naturally and elegantly explains the origin of the baryon and dark matter asymmetries, and clearly gives the close interrelations of them. In addition, the model predicts a number of interesting results, e.g. the cold dark matter neutrino mass is $3.1$ times the proton mass. It is also feasible and promising to test the model in future experiments.
