Effective Theories of Flavor and the non-Universal MSSM

Flavor symmetries a la Froggatt-Nielsen (FN) provide a compelling way to explain the hierarchies of fermionic masses and mixing angles in the Yukawa sector. In Supersymmetric (SUSY) extensions of the Standard Model where the mediation of SUSY breaking occurs at scales larger than the breaking of flavor, this symmetry must be respected not only by the Yukawas of the superpotential, but by the soft-breaking terms as well. Here, I will show that contrary to naive expectations, even starting with completely flavor blind soft-breaking at high scales, the low-energy sfermion mass matrices and trilinear terms of the effective theory are strongly non-universal. We apply these ideas to some representative flavor models in order to study their phenomenology with a particular emphasis on the leptonic flavor observables.
