Abstract

Fiducial and total 𝑊 ± and 𝑍 boson cross sections, their ratios and the ratio of top-antitop-quark pair and 𝑊-boson fiducial cross sections are measured in proton–proton collisions at a centre-of-mass energy of √𝑠= 13.6TeV, corresponding to an integrated luminosity of 29 fb−1 of data collected in 2022 by the ATLAS experiment at the Large Hadron Collider. The measured fiducial cross-section values for 𝑊 + → 𝓁+𝜈, 𝑊 − → 𝓁−̄ 𝜈, and 𝑍 → 𝓁+𝓁− (𝓁 =𝑒 or 𝜇) boson productions are 4250 ±150pb, 3310 ±120pb, and 744 ±20pb, respectively, where the uncertainty is the total uncertainty, including that arising from the luminosity of about 2.2%. The measurements are in agreement with Standard-Model predictions calculated at next-to-next-to-leading-order in 𝛼𝑠, next-to-nextto-leading logarithmic accuracy and next-to-leading-order electroweak accuracy.
