Description
We report the most general expression for the chiral charges of a non-universal U(1)' with identical
charges for the first two families but different charges for the third one. The model is minimal in the
sense that only standard model fermions plus right-handed neutrinos are required. By imposing anomaly
cancellation and constraints coming from Yukawa couplings we obtain two different solutions. In one of
these solutions, the anomalies cancel between fermions in different families. These solutions depend on
four independent parameters which result very useful for model building. We build different benchmark
models in order to show the flexibility of the parameterization. We also report LHC and low energy
constraints for these benchmark models.
