Local Baryon Number at the LHC

Abstract

The minimal theory in which baryon number is spontaneously broken at the low scale predicts new fermions, one of which is a dark matter candidate, from gauge anomaly cancellation. We discuss the production mechanisms and decays of these new fermions, which include channels with multi-leptons, and channels with long-lived charged fermions that can give rise to exotic signatures with 'kinked' tracks at the Large Hadron Collider. We evaluate the contraints on the theory from current LHC searches and measurements, and briefly comment on the excess in top pair production at threshold recently reported by CMS. We also discuss predictions for the $h\to \gamma Z_B$ decay, where $h$ is the SM-like Higgs and $Z_B$ is the new gauge boson associated with baryon number.
