Predictions from a flavour-GUT model combined with a SUSY breaking sector — •Christian Hohl¹ and Stefan Antusch^1,2 — ¹University of Basel, Switzerland — ²Max-Planck-Institut für Physik, München, Germany

We discuss how flavour GUT models in the context of supergravity can be completed with a simple SUSY breaking sector, such that the flavour-dependent (non-universal) soft breaking terms can be calculated. As an example, we discuss a model based on an SU(5) GUT symmetry and A₄ family symmetry, plus additional discrete “shaping symmetries” and an Z₄^R symmetry. We calculate the soft-terms and identify the relevant high scale input parameters, and investigate the resulting predictions for the low scale observables, such as e.g. for flavour processes, the sparticle spectrum and for the dark matter relic density.
