Impact of the Higgs discovery on two models of new physics

A combined fit of electroweak precision data and data on Higgs decays lead to an exclusion of the Standard Model with a sequential fourth generation at the level of 5 standard deviations. In my talk I discuss the methodology of the corresponding statistical analysis, which involved so-called non-tested hypotheses. Then I discuss a supersymmetric GUT model, in which the atmospheric neutrino mixing angle affects b->s transitions. The model, originally proposed by Chang, Masiero and Murayama, can accomodate the mass of 126 GeV of the lightest neutral Higgs boson and naturally comes with 11 heavy squarks and a fairly light right-handed top squark.
