New Forces and the 750 GeV Resonance

TL;DR

This paper explores the hypothesis that a 750 GeV resonance observed at the LHC could be a new scalar field linked to a spontaneously broken baryon number gauge symmetry, predicting new particles and forces.

Contribution

It proposes a simple model where the 750 GeV resonance is a Higgs-like scalar from baryon number symmetry breaking, introducing new vector-like quarks and predicting a new force detectable at the LHC.

Findings

Sets an upper bound on the symmetry breaking scale.

Predicts the existence of a new force associated with baryon number.

Suggests the resonance could be a Higgs-like scalar from baryon symmetry breaking.

Abstract

Recently, the ATLAS and CMS collaborations have pointed out the possible existence of a new resonance with a mass around 750 GeV. We investigate the possibility to identify this new resonance with a spin zero field responsible for the breaking of a new gauge symmetry. We focus on a simple theory where the baryon number is a local symmetry spontaneously broken at the low scale. In this context new vector-like quarks are needed to cancel all baryonic anomalies and define the production mechanism and decays of the new Higgs at the LHC. Assuming the existence of the new Higgs with a mass of 750 GeV at the LHC we find an upper bound on the symmetry breaking scale. Therefore, one expects that a new force associated with baryon number could be discovered at the LHC.
