From Flavour to SUSY Flavour Models — Stefan Antusch1, Lorenzo Calibbi1, •Vinzenz Maurer1, and Martin Spinrath2 — 1Max-Planck-Institut fuer Physik, Muenchen, Deutschland — 2SISSA, Trieste, Italy
If supersymmetry (SUSY) will be discovered, models of flavour have to provide not only an explanation for the flavour structure of the Standard Model fermions but also of their scalar superpartners. In this talk we show how a conventional flavour model might be extended in this context to a SUSY flavour model. As an example, we analyse a new class of flavour models realised in a SU(5) Grand Unified Theory where the 5 representation fields are unified in a real triplet representation of a family symmetry group such as SO(3) or A4, which is then extended into a SUSY flavour model. We take into account important SUSY specific corrections such as 1-loop SUSY threshold corrections and canonical normalisation effects. Using this we fit the model to the data of fermion masses and mixings. From this we make predictions for the SUSY spectrum as well as for the neutrino sector which can be tested by ongoing and future experiments.
