Description
Aim of the meeting:
This informal meeting is intended for extensive discussions on phenomenological issues of mutual interest  between the participants: mainly flavor physics, but also axion phenomenology and dark sectors. A certain number of more formal seminars will be open to the general audience. On Wednesday 27/6, 2:30pm in "Aula Salvini" Prof. G. Martinelli (U. La Sapienza) will deliver the General Seminar: "Flavor Physics for Non-Experts: (a Theory) Overview". 
Speakers:
Tuesday 26/6, 2.30pm:  Giuliano Panico (IFAE Barcellona)
"Flavor and Compositeness" 
Wednesday 27/6, 10:00am:  Federico Mescia (Barcellona Univ.)
"Present status of B anomalies" 
Wednesday 27/6, 11:00am:  Luca Di Luzio (Durham Univ.)
"From 321 to 4321: a Cabibbo mechanism for leptoquarks"

"Flavor Physics for Non-Experts: (a Theory) Overview
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.

      Flavor and compositeness 1h
      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.

      I will present an update about the present status of the various anomalies observed in B physics.

      From 321 to 4321: a Cabibbo mechanism for leptoquarks 1h
      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.
