The dataset corresponds to an integrated luminosity of 139 fb$^{-1}$. Events with exactly one charged lepton and four or more jets in the final state, with at least one jet containing $b$-hadrons, are used to determine the $t\\bar{t}$ production cross-section through a profile-likelihood fit. The inclusive cross-section is measured to be ${\\sigma_{\\text{inc}} = 830 \\pm 0.4 \\text{(stat.)} \\pm 36 \\text{(syst.)}\\pm 14 \\text{(lumi.)} \\mathrm{pb}}$ with a relative uncertainty of 4.6 %. The result is consistent with theoretical calculations at next-to-next-to-leading order in perturbative QCD.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.95748.v2/t1","@type":"Dataset","description":"The results of fitted inclusive and fiducial ${t\\bar{t}}$ cross-sections","name":"Fitted cross-sections"},{"@id":"https://doi.org/10.17182/hepdata.95748.v2/t2","@type":"Dataset","description":"Ranking of the systematic uncertainties on the measured cross-section, normalised to the predicted value, in the inclusive fit to data....","name":"Ranking Inclusive"},{"@id":"https://doi.org/10.17182/hepdata.95748.v2/t3","@type":"Dataset","description":"Ranking of the systematic uncertainties on the measured cross-section, normalised to the predicted value, in the fiducial fit to data....","name":"Ranking Fiducial"},{"@id":"https://doi.org/10.17182/hepdata.95748.v2/t4","@type":"Dataset","description":"Impact of different categories of systematic uncertainties on the fiducial and inclusive measurements.
