Theory for Baryon Number and Dark Matter at the LHC

TL;DR

This paper explores a gauge theory where baryon number is spontaneously broken at low energies, predicting new particles that can be tested at the LHC and linked to dark matter constraints.

Contribution

It provides a theoretical framework connecting baryon number violation, a leptophobic gauge boson, and dark matter, with testable collider signatures and relic density constraints.

Findings

Upper bound on symmetry breaking scale from relic density

Predicted leptophobic gauge boson accessible at colliders

Connection established between collider signals and dark matter constraints

Abstract

We investigate the possibility to test the simplest theory for spontaneous baryon number violation at the Large Hadron Collider. In this context the baryon number is a local gauge symmetry spontaneously broken at the low scale through the Brout-Englert-Higgs mechanism. This theory predicts the existence of a leptophobic neutral gauge boson and a fermionic dark matter candidate with baryon number. We study the gauge boson and Higgs decays, and explore the connection between collider signatures and constraints coming from dark matter experiments. We point out an upper bound on the symmetry breaking scale using the relic density constraints which tells us that this model can be tested or ruled out at current or future collider experiments.
