Anomaly-Free Dark Matter Models are not so Simple
We explore the anomaly-cancellation constraints on simplified dark matter (DM) models with an extra U(1)$^{′}$ gauge boson Z$^{′}$. We show that, if the Standard Model (SM) fermions are supplemented by a single DM fermion χ that is a singlet of the SM gauge group, and the SM quarks have non-zero U(1...
