Description
The Standard Model of particles describes the fundamental constituents of matter and their interactions. Its predictions are probed in measurements at the LHC. In this talk, recent measurements by the ATLAS experiment are presented. They range from measurements of multijet and -photon production, high precision measurements using single W or Z bosons to measurements of multiboson production. Particular highlights are measurements that determine the strong coupling constant alpha_S and the W boson mass. Moreover, high-precision, differential measurements of multijet event shapes, the pT of the W and Z bosons, and the production of vector bosons in association with jets are discussed. They probe perturbative QCD and are compared to state-of-the-art theoretical predictions. Furthermore, measurements sensitive to trilinear and quartic electroweak gauge couplings are presented. These test the gauge structure of the electroweak theory and the agreement of the measurements with data are quantified by setting limits on Wilson Coefficients in the Standard Model Effective Field Theory.
