• The 331 models constitute an extension of the Standard Model (SM) obtained by enlarging the SM gauge group SU (3)C × SU (2)L × U (1)Y to the group SU (3)C × SU (3)L × U (1)X. We investigate how a nonminimal 331 model may embed lepton flavor universality violating contributions to b → sℓℓ processes without introducing lepton flavor violation, as suggested by the recent LHCb measurements of the ratios RK and RK*. We discuss the model-independent scenarios of new physics in b → sℓℓ currently favored by the data that could be accommodated by this model and consider a few phenomenological constraints on this model.
