A bstractWe treat the Standard Model as the low-energy limit of an effective field theory that incorporates higher-dimensional operators to capture the effects of decoupled new physics. We consider the constraints imposed on the coefficients of dimension-6 operators by electroweak precision tests (EWPTs), applying a framework for the effects of dimension- 6 operators on electroweak precision tests that is more general than the standard S, T formalism, and use measurements of Higgs couplings and the kinematics of associated Higgs production at the Tevatron and LHC, as well as triple-gauge couplings at the LHC. We highlight the complementarity between EWPTs, Tevatron and LHC measurements in obtaining model-independent limits on the effective Standard Model after LHC Run 1. We illustrate the combined constraints with the example of the two-Higgs doublet model.

How to use the Standard Model effective field theory (2014, background): “J H E P 0 1 ( 2 0 1 6 ) 0 2 3 have been a variety of studies concerning the mapping of operators onto weak-scale observables in the literature [18, 28, 30, 31, 36–53], to the best of our knowledge, a complete and systematic list does not exist yet.”
Higgs Physics at the HL-LHC and HE-LHC (2019, methodology): “In this note, after reviewing the SMEFT framework and our previous results [749, 750, 751, 752], we present projections for the prospective sensitivities of measurements with the approved High-Luminosity LHC (HL-LHC) project and the proposed High-Energy LHC (HE-LHC) project to Wilson coefficients.”

Updated global SMEFT fit to Higgs, diboson and electroweak data (2018, background): “Furthermore, many such analyses already exist, both within [18, 129, 130] and outside [119, 131, 132] the EFT framework.”
A Monte Carlo global analysis of the Standard Model Effective Field Theory: the top quark sector (2019, unknown): “In this context, the wealth of precision measurements presented by the LHC collaborations in recent years, together with the significant progress in the corresponding theoretical calculations and modelling of collider processes, has motivated many groups to pursue (partial) SMEFT analyses of the LHC”
