Description

Precision measurements of W, Z and Higgs boson production are presented. Such measurements are powerful probes of the electroweak sector of the Standard Model as well as proton structure. First, the new results from ATLAS that include the world first measurements of the complete set of angular coefficients and full phase-space differential cross-sections of W boson production is summarized. The measurements use low pileup data which allow an optimised reconstruction of the W boson transverse momentum. Then, this talk presents precise measurements of Higgs boson production and decay rates, obtained using the full Run 2 and partial Run 3 pp collision dataset collected by the ATLAS experiment at 13 TeV and 13.6 TeV. These include total and fiducial cross-sections for the main Higgs boson processes as well as branching ratios into final states with bosons and fermions. Differential cross-sections in a variety of observables are also reported, as well as a fine-grained description of the Higgs boson production kinematics within the Simplified Template Cross-section (STXS) framework.
