Collider probes of a gauged U(1) baryon number

Abstract: I discuss the current status of collider constraints on dijet resonances from the ATLAS and CMS experiments and an interpretation in the context of a gauged U(1) baryon number.  I also discuss the field content of minimal ultraviolet completions of such an anomalous U(1) symmetry and their collider phenomenology, including diphoton and 4-jet resonances.  I also discuss the role of the exotic Z -> Z' + photon decay in probing anomalous currents involving SM fields.
