Dirac fermion dark matter models with heavy \(Z^{\prime}\) mediators are subject to stringent constraints from spin-independent direct searches and from LHC bounds, cornering them to live near the \(Z^{\prime}\) resonance. Such constraints can be relaxed, however, by turning off the vector coupling...
