Description
I will discuss an extension of the Standard Model (SM) by a full new generation of quarks and leptons which are vector-like (VL) under the SM gauge group but chiral with respect to a new flavor dependent U(1) gauge symmetry. The model can simultaneously explain the deviations of the muon g-2 and lepton flavor universality in B-meson decays without conflicting with the data on Higgs decays, lepton flavor violation, or B-Bbar mixing. Fitting the anomalies, the model predicts VL quarks, leptons and a massive Z', all at the TeV scale. Furthermore, Lepton-flavor violating tau decays to three muons or mu+gamma are predicted to be within reach of Belle II. For model building, an interesting feature of the model is the automatic suppression of flavor changing Higgs, Z, and Z' couplings to SM generations which we have understood analytically.
