Generic SUSY GUT models suffer from the problem that Planck scale induced operators lead to the proton decay requiring some suppression of the couplings to make them compatible with current experimental bounds. I will review the problem of proton decay in such models and present a GUT model based on the SO(10) group where the operators leading to the proton decay can be suppressed due to...

Typically, only the minimal GUTs can be subject to a thorough scrutiny by complementary observables such as the proton lifetime, the absolute neutrino mass scale and the matching with the effective SM flavor structure. In this respect, the concept of minimality itself can be associated to the simplicity of the relevant Higgs sector. I will review some recent results on the Higgs sector of both...

We consider supersymmetric models where anomaly- and gravity mediation give comparable contributions to the soft terms. An Abelian flavor symmetry is invoked to explain both the observed matter flavor structure and an alignment of the sparticles. As an illustration, we present an example where the constraints from flavor- and CP violation, such as coming from mu --> e + gamma and EDMs, are...
