摘要
We consider an anomaly free U(1)' model with favorable couplings to heavy flavors in the Standard Model ( SM), as motivated by B- meson anomalies at LHCb. Taking the U(1)' charge to be Q' = y(L mu - L tau) + x(B-3 - L-3), we can explain theB- meson anomalies without invoking extra charged fermions or flavor violation beyond the SM. We showthat there is a viable parameter space with a small x that is compatible with other meson decays, tau lepton, and neutrino experiments as well as theLHCdimuon searches. We briefly discuss the prospects of discovering the Z' gauge boson at the LHC in the proposed model.
