The Effective Standard Model: A Comprehensive Approach to Decoupled New Physics
Tevong You (Kings College London)

The main lesson learned from Run I of the LHC is that new physics beyond the Standard Model (SM) is either hidden within the kinematic reach of the LHC or decoupled at higher energies. Furthermore the Higgs boson has finally been discovered and seems to be SM-like to a first approximation. Motivated by these two facts, we consider a systematic approach to decoupled new physics in the electroweak and Higgs sector by constraining a complete set of dimension-6 operators that parametrise the leading effects of the SM effective field theory. Lower limits are placed on the energy scale at which new degrees of freedom may enter into electroweak precision tests at LEP as well as triple-gauge-couplings at the LHC and Higgs physics at the Tevatron and LHC. Such a model-independent approach highlights the complementary between different measurements and experiments.
