In search of an invisible Z′
Abstract We consider extending the Standard Model by an anomaly-free and possibly flavour non-universal U(1) X gauge symmetry, whose breaking gives a Z′ boson that does not affect electroweak precision observables at tree-level or via 1-loop renormalisation group (RG) running. Provided it does not a...
