Abstract

We explore a Z′ boson coupled only with the Standard Model (SM) fermions (Z′ff) in the framework of minimal flavor violation. We study its effects on the processes with lepton flavor violation j→ik̄l, j→iγ, μ-N→e-N, quark flavor-changing neutral currents b→s, neutral B and K meson mixing, and e+e-→ff at the LEP experiment to constrain the parameter space of Z′ mass and couplings. We find that among those relevant processes, μ→eγ, μ→3e, μ-e conversion and e+e-→ff can put more stringent bounds on Z′ff couplings normalized by Z′ mass. The implications for various processes are obtained, such as B and K mixing and B/K→M12 decays. In addition, we also analyze Z′ signatures at the LHC with s=8 and 13 TeV.
