An attractive solution to the naturalness problem is to require that the Higgs is a composite state arising from some strongly-coupled sector at TeV energies. This possibility has important implications for the theory of flavor, in particular it implies that the origin of the flavor structure must be addressed at low energy. The traditional composite-Higgs flavor models based on the partial compositeness idea (anarchic flavor scenarios) are in tension with the experimental data. New constructions in which the flavor hierarchies arise dynamically from the UV can remove this tension, providing a strong reduction in flavor-changing and CP-violating effects. These new models predict a distinctive pattern of signatures that could be tested in near-future experiments.

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.

Flavor Physics for Non-Experts: (a Theory) Overview
- Guido Martinelli (ROMA1)
14:30 - 15:30
Several aspects of flavour physics, including the recent experimental ``anomalies” in leptonic decays, are critically reviewed. New ideas to improve the accuracy of the theoretical predictions and future developments are discussed.
