=== Model Description

We consider consistent dark matter models with a spin-1 mediator Z' and a dark matter
fermion χ, charged under the new gauge group. The available options are purely singlet
SM fermions, gauged lepton number differences, or the well-known anomaly-free difference
between the lepton and baryon numbers
