Fiducial and total W&sup(*() 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 = 13.6 TeV, 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*+*n, W*- *>l*-*n^-, and Z *> l*+l*-(l = e or *m) boson productions are 4250 *( 150 pb, 3310 *( 120 pb, and 744*( 20 pb, 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 , next-to-next-to-leading logarithmic accuracy and next-to-leading-order electroweak accuracy.
