Baryonic Higgs and Dark Matter

TL;DR

This paper explores how a baryonic Higgs boson in gauge theories linked to dark matter can decay into photons or dark matter particles, with implications for collider experiments.

Contribution

It introduces a minimal gauge theory for baryon number where the Higgs responsible for symmetry breaking also generates dark matter mass, analyzing its decay channels and collider signatures.

Findings

Higgs can have large branching ratios into two photons or dark matter.

Constraints from dark matter density and detection limit the Higgs decay modes.

Unique collider signatures are discussed for the Large Hadron Collider.

Abstract

We discuss the correlation between dark matter and Higgs decays in gauge theories where the dark matter is predicted from anomaly cancellation. In these theories, the Higgs responsible for the breaking of the gauge symmetry generates the mass for the dark matter candidate. We investigate the Higgs decays in the minimal gauge theory for Baryon number. After imposing the dark matter density and direct detection constraints, we find that the new Higgs can have a large branching ratio into two photons or into dark matter. Furthermore, we discuss the production channels and the unique signatures at the Large Hadron Collider.
