Abstract A plethora of ultraviolet completions of the Standard Model have extra U(1) gauge symmetries. In general, the associated massive Z ′ gauge boson can mediate flavor-changing neutral current processes at tree level. We consider a situation where the Z ′ boson couples solely via flavor-changin...
