Heavy Charged Gauge Bosons with General CP Violating Couplings

Abstract: Heavy gauge bosons such as W ′ are expected to exist in many extensions of the Standard Model. In this paper, it is shown that the most general Lagrangian for the interaction of W ′ with top and bottom quarks which consists of V-A and V+A structure with in general complex couplings produces an Electric Dipole Moment (EDM) for the top quark at one loop level. We predict the allowed ranges for the mass and couplings of W ′ by using the upper limit on the top quark EDM.
