ATLAS EFT results in the top quark sector

With no evidence of direct production of beyond the Standard Model (BSM) particles 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). The SMEFT, a framework for probing BSM effects, extends the SM by introducing higher-dimensional operators parameterized by Wilson coefficients. This contribution highlights three recent analyses using the ATLAS Run-2 dataset at a center-of-mass energy of \sqrt{s} s = 13 TeV with an integrated luminosity of 140 \text{fb}^{-1} fb − 1 . Combined measurements enhance sensitivity to Wilson coefficients, exploring the potential of SMEFT in the top quark sector.
