Abstract
The largest global symmetry that can be made local in the Standard Model+3νR while being compatible with Pati-Salam unification is SU(3)H×U(1)B-L. The gauge bosons of this theory would induce flavor effects involving both quarks and leptons, and are a potential candidate to explain the recent reports of lepton universality violation in rare B-meson decays. In this paper we characterize these types of models and show how they can accommodate the data and naturally be within reach of direct searches.
