: We discuss a simple theory predicting the existence of a Dirac dark matter candidate from gauge anomaly cancellation. In this theory, the spontaneous breaking of local baryon number at the low scale can be understood. We show that the constraint from the dark matter relic abundance implies an upper bound on the theory of a few tens of TeV. We study the correlation between the dark matter constraints and the prediction for the electric dipole moment (EDM) of the electron. We point out the implications for the diphoton decay width of the Standard Model Higgs. Furthermore, we study the decays of the new Higgs present in the theory, we show that the branching ratio into two photons can be large and discuss the correlation between the dark matter constraints and the properties of the new Higgs decays. This theory could be tested at current or future experiments by combining the results from dark matter, collider and EDM experiments.
