Dark matter, lepton and baryon number, and left-right symmetric theories

TL;DR

This paper explores a lepto-baryonic left-right symmetric theory that naturally includes stable dark matter candidates, discusses anomaly cancellation solutions, and identifies viable dark matter particles like neutral fermion triplets.

Contribution

It introduces a novel lepto-baryonic left-right symmetric framework with automatic dark matter stability and analyzes anomaly-free solutions and dark matter candidates.

Findings

Neutral fermion triplet can be a viable dark matter candidate.

Theories are generally anomalous; solutions for anomaly cancellation are presented.

Multiple dark matter possibilities are discussed within the framework.

Abstract

A lepto-baryonic left-right symmetric theory is considered along with pointing out stable dark matter candidates whose stability is ensured automatically where leptons and baryons are defined as local gauge symmetries. These theories are generally anomalous and the possible gauge anomaly free solutions for these theories are presented. It is found that the neutral component of fermion triplets can be a viable dark matter candidate originally introduced for gauge anomaly cancellation. The other dark matter possibilities within this lepto-baryonic left-right symmetric theory are also presented.
