Abstract
| The LHCb Collaboration has recently reported hints for New Physics in b → ss + −
transitions that point to a large violation of flavor universality in the lepton
sector. Motivated by them, we present a framework able to accommodate the
experimental anomalies while, at the same time, addressing the flavor puzzle of
the Standard Model. This framework is based on the hypothesis of dynamical
Yukawas, where it is assumed that these couplings are generated by the vacuum
expectation value of dynamical fields charged under a local non-Abelian flavor
symmetry. The proposed framework has a rich phenomenology and predicts striking
collider signatures that will be tested in the near future. |
