Higgs boson coupling measurements in ATLAS

The discovery of a Higgs boson with a mass around 125 GeV by the ATLAS and CMS experiments has opened a window into a fundamental sector of the Standard Model. Precise measurements of this new particle's properties provide essential tests of the Standard Model's consistency. This article presents a selection of measurements and searches performed by the ATLAS experiment, based on 140 fb$^{-1}$ of $\sqrt{s}=13$ TeV $pp$ collision data collected during LHC Run 2. The latest determinations of Higgs boson couplings across various decay channels are reported, utilizing production mode cross-section measurements and the detailed kinematic description offered by the Simplified Template Cross Sections framework. Combinations of these results are also discussed.
