Augury of darkness: the low-mass dark Z ′ portal
Abstract Dirac fermion dark matter models with heavy Z ′ mediators are subject to stringent constraints from spin-independent direct searches and from LHC bounds, cornering them to live near the Z ′ resonance. Such constraints can be relaxed, however, by turning off the vector coupling to Standard M...
