Minimal $Z'$ models for flavor anomalies

Understand

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.
