Description
After reviewing the status of the recent experimental discrepancies in B-physics data, I show how these phenomena can be coherently explained by an extended gauge dynamics which closely mimics the structure of the standard model. A key role is played by a generalisation of the Cabibbo mixing which allows for sizeable effects in charged current quark-lepton transitions, while sufficiently suppressing quark-quark and lepton-lepton FCNC. The model is also consistent with direct searches at high-pT and provides a fully calculable framework to guide the early phase of the B-anomalies and predict correlations with new observables.
