摘要: We perform the t of electroweak precision observables within Standard Model with a 126 GeV Higgs boson, compare results theoretical predictions and discuss impact recent experimental improvements. introduce New Physics contributions in model-independent way for S, T U parameters, 1;2;3;b ones, modied Zb b couplings coupling to vector bosons. point out that composite models are very strongly constrained. Finally, we compute bounds on dimension-six operators relevant t.
