Abstract
- By allowing gauge anomaly cancellation between fermions in different families we find a non-universal solution for a Z′ family of models with the same content of fermions of the standard model plus three right-handed neutrinos. We also impose constraints from the Yukawa interaction terms in such a way that at the end we obtain a solution with six free parameters. Our solution contains as particular cases well-known models in the literature. As an application, we report a model that evades LHC constraints, flavor changing neutral currents and low energy constraints. Simultaneously, the model is able to explain the flavor anomalies in the Wilson coefficients C9(μ) and C10(μ) without modifying the corresponding Wilson coefficients for the first family. In our approach, this procedure is always possible for Z′ masses smaller than ∼2.5 TeV. [ABSTRACT FROM AUTHOR]
