Abstract: (APS)

The Standard Model (SM) is amended by one generation of quarks and leptons which are vectorlike (VL) under the SM gauge group but chiral with respect to a new U(1)3-4 gauge symmetry. We show that this model can simultaneously explain the deviation of the muon g-2 as well as the observed anomalies in b→sμ+μ- transitions without conflicting with the data on Higgs decays, lepton flavor violation, or Bs-B¯s mixing. The model is string theory motivated and Grand Unified Theory compatible, i.e. UV complete, and fits the data predicting VL quarks, leptons, and a massive Z′ at the TeV scale, as well as τ→3μ and τ→μγ within reach of future experiments. The Higgs couplings to SM generations are automatically aligned in flavor space.
