Unification of SUSY breaking and GUT breaking

In this talk, I introduce explicit supersymmetric unification models where grand unified gauge symmetry breaking and supersymmetry (SUSY) breaking are caused by the same sector. In this model, the SM-charged particles are also predicted by the symmetry breaking sector, and they play a role in giving the soft SUSY breaking terms through the so-called gauge mediation. We investigate the mass spectrums in an explicit model with SU(5) and additional gauge groups, and discuss the phenomenology. Especially, nonzero A-term and B-term are generated according to the mediation via the vector superfields, so that the electro-weak symmetry breaking and 126 GeV Higgs may be achieved by the large B-term and A-term even if the stop mass is around 1 TeV.
