Flavor Hierarchies from a Minimal U(2) Symmetry

Dr. Anders E. Thomsen , Bern

We explore the possibility that the distinct patterns observed in fermion masses and mixings may be due to a minimally-broken U(2) flavor symmetry giving rise to an accidental U(2)^5 symmetry in the Yukawa couplings of the charged fermions. In model-independent analysis we find that the selection rules of the U(2) symmetry enhances the importance of charge lepton flavor violation as a probe for new physics. I will also present an economical realization of the framework with a renormalizable model, which links all flavor hierarchies to a single hierarchy of scales at high energies. The model has a rich phenomenology with promising signatures, especially in the context of K and B meson physics.
