Vectorlike chiral fourth family to explain muon anomalies
Abstract
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 – $$ \overline{B}\ $$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.
