Using events with an opposite-charge electron-muon pair and $b$-tagged jets, and assuming Standard Model decays, the top-quark-pair production cross section is measured to be $\\sigma_{t\\bar{t}} = 850 \\pm 3\\mathrm{(stat.)}\\pm 18\\mathrm{(syst.)}\\pm 20\\mathrm{(lumi.)}$ pb. The ratio of the $t\\bar{t}$ and the $Z$-boson production cross sections is also measured, where the $Z$-boson contribution is determined for inclusive $e^+e^-$ and $\\mu^+\\mu^-$ events in a fiducial phase space. The relative uncertainty on the ratio is reduced compared to the $t\\bar{t}$ cross section, thanks to the cancellation of several systematic uncertainties. The result for the ratio, $R_{t\\bar{t}/Z} = 1.145 \\pm 0.003\\mathrm{(stat.)}\\pm 0.021\\mathrm{(syst.)}\\pm 0.002\\mathrm{(lumi.)}$ is consistent with the Standard Model prediction using the PDF4LHC21 PDF set.","name":"Measurement of the $t\\bar{t}$ cross section and its ratio to the $Z$ production cross section using $pp$ collisions at $\\sqrt{s} = 13.6$ TeV with the ATLAS detector","url":"https://www.hepdata.net/record/ins2689657?version=1"},"keywords":"P P --> TOP TOPBAR X, P P --> LEPTON+ LEPTON- X, Inclusive, Fiducial, Cross Section, Top quark pair production, Z Production, 13600","name":"$Z$-boson phase-space","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/151784","version":1}
