We propose an extension of the standard model with an extra Uð1Þ 0 Abelian symmetry, three Higgs doublets and two Higgs singlets, where the new Uð1Þ 0 charges are flavor nonuniversal. As a result, the model introduces an enlarger particle spectrum in the TeV scale with large new physics possibilities. The model reproduces the mixing angles and mass structures of the quarks, charged and neutral leptons. We found scenarios where the observed anomaly of the B þ → K þ ll decay can be explained due to the existence of couplings with new extra fermions at the TeV scale. By modifying the parametrization of the mixing matrices, we found solution in the decoupling limit.
