Abstract

In models with an extra U(1)′ gauge boson family non-universal couplings to the weak eigenstates of the standard model fermions generally induce flavor-changing neutral currents. This phenomenon leads to interesting results in various B meson decays, for which recent data indicate hints of new physics involving significant contributions from b→s transitions. We analyze the Bs system, emphasizing the effects of a Z′ on the mass difference and CP asymmetries.
