Description

The origin of masses and mixings of the three families of fermions remains one of the main problems of the Standard Model. Flavor symmetries provide a compelling way to explain these of arbitrary parameters in the Yukawa sector. In Supersymmetric 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 masses and trilinear terms as well. In this case, even starting with completely flavor blind soft-breaking in the full theory at high scales, the low-energy sfermion mass matrices and trilinear terms of the effective theory, obtained upon integrating out the heavy mediator fields, are strongly non-universal. We explore the phenomenology of several SUSY flavor models after the latest LHC searches for new physics.
