Seminarium Teorii Oddziaływań Elementarnych

I will discuss the interpretation of collider data in the framework of effective field theory beyond the standard model (SM). This involves extending the SM Lagrangian by a completely general set of operators of dimension 6. One effect of these operators is to modify the couplings of the SM Higgs and gauge bosons away from the SM prediction. In the talk I will discuss the current constraints on dimension-6 operators. I will put a special focus on the synergy between the LHC Higgs data and LEP electroweak precision observables.
