# Baryonic Higgs at the LHC

## TL;DR

This paper explores the collider signatures of a new Baryonic Higgs in models with local baryon number symmetry, analyzing constraints from LHC searches and the potential for discovery through various decay channels.

## Contribution

It provides a detailed analysis of the Baryonic Higgs properties, decay modes, and constraints from LHC data, highlighting the di-photon channel as a key probe for the baryonic scale.

## Key findings

- Di-photon channel strongly constrains the baryonic scale at low scalar mixing.
- LHC searches for $Z Z$, $W W$, and $ ext{γγ}$ channels set lower bounds on the symmetry breaking scale.
- Properties of the leptophobic gauge boson are characterized for future testability.

## Abstract

We investigate the possible collider signatures of a new Higgs in simple extensions of the Standard Model where baryon number is a local symmetry spontaneously broken at the low scale. We refer to this new Higgs as "Baryonic Higgs". This Higgs has peculiar properties since it can decay into all Standard Model particles, the leptophobic gauge boson, and the vector-like quarks present in these theories to ensure anomaly cancellation. We investigate in detail the constraints from the $\gamma \gamma$, $Z \gamma$, $Z Z$, and $W W$ searches at the Large Hadron Collider, needed to find a lower bound on the scale at which baryon number is spontaneously broken. The di-photon channel turns out to be a very sensitive probe in the case of small scalar mixing and can severely constrain the baryonic scale. We also study the properties of the leptophobic gauge boson in order to understand the testability of these theories at the LHC.
