Title: Z’ bosons in light of B-anomalies
Abstract: Many measurements of b->s transitions (when accompanied by a di-muon pair) disagree with state-of-the-art Standard Model (SM) predictions. On the other hand, many other measurements, including those measuring lepton flavour universality, are in rough agreement with the SM.
We shall review such measurements and give a broad overview of the SM predictions. Z’ bosons with family-dependent couplings can significantly improve global fits. We give an example of a successful model, re-cast LHC searches for it and provide HL-LHC sensitivity estimates.
