ATLAS EFT Results in the Top Quark Sector / Kim, Dongwon (Stockholm U. (main) ; Stockholm U., OKC)
With no direct evidence for new physics at the TeV scale, deviations from the Standard Model (SM) can be explored systematically through Effective Field Theories (EFTs) such as the Standard Model EFT (SMEFT). [...]

ATLAS EFT Results in the Top Quark Sector / Kim, Dongwon (Stockholm University (SE)) /ATLAS Collaboration
The overview summarises the latest Effective Field Theory (EFT) analyses conducted by the ATLAS experiment, focusing on latest results in constraining physics beyond the Standard Model using precision measurements. Emphasis is placed on the top quark sector, where EFT provides a powerful framework for interpreting deviations in top quark production and decay processes. [...]

EFT constraints from top quark measurements in CMS / Zimermmane Castro Santos, Andre (DESY) /CMS Collaboration
Effective Field Theories (EFTs) offer a systematic way of parametrising small deviations from the Standard Model (SM) originating from new phenomena. In the top quark sector, by using the full potential of the second run of the LHC, the CMS collaboration is able to perform precision measurements of well-studied top interactions as well as measure rarer top processes [...]

Measurements and EFT fits on detector level / Mohrman, Kelci (Florida U.)
The framework of standard model effective field theory (SMEFT) provides a relatively model-agnostic tool with which to parameterize the off-shell effects of potential heavy new physics. [...]

Top, Higgs, Diboson and Electroweak Fit to the Standard Model Effective Field Theory / Ellis, John (King's Coll. London ; CERN ; NICPB, Tallinn) ; Madigan, Maeve (Cambridge U., DAMTP) ; Mimasu, Ken (King's Coll. London) ; Sanz, Veronica (Valencia U., IFIC ; Sussex U.) ; You, Tevong (CERN ; Cambridge U., DAMTP ; Cambridge U.)
The search for effective field theory deformations of the Standard Model (SM) is a major goal of particle physics that can benefit from a global approach in the framework of the Standard Model Effective Field Theory (SMEFT). For the first time, we include LHC data on top production and differential distributions together with Higgs production and decay rates and Simplified Template Cross-Section (STXS) measurements in a global fit, as well as precision electroweak and diboson measurements from LEP and the LHC, in a global analysis with SMEFT operators of dimension 6 included linearly. [...]

Dimension-6 Operator Analysis of the CLIC Sensitivity to New Physics / Ellis, John (King's Coll. London ; CERN) ; Roloff, Philipp (CERN) ; Sanz, Veronica (Sussex U.) ; You, Tevong (Cambridge U.)
We estimate the possible accuracies of measurements at the proposed CLIC $e^+e^-$ collider of Higgs and $W^+W^-$ production at centre-of-mass energies up to 3TeV, incorporating also Higgsstrahlung projections at higher energies that had not been considered previously, and use them to explore the prospective CLIC sensitivities to decoupled new physics. We present the resulting constraints on the Wilson coefficients of dimension-6 operators in a model-independent approach based on the Standard Model effective field theory (SM EFT). [...]

Effective Field Theory for Higgs properties parametrisation: the transverse momentum spectrum case / Grazzini, Massimiliano (Zurich U.) ; Ilnicka, Agnieszka (Zurich U. ; Zurich, ETH ; PSI, Villigen) ; Spira, Michael (PSI, Villigen) ; Wiesemann, Marius (Zurich U. ; CERN)
After the Higgs boson discovery, LHC can be used as a precision machine to explore its properties. Indeed, in case new resonances will not be found, the only access to New Physics would be via measuring small deviations from the SM predictions. [...]
