{"title": "Measurement of the $t\\bar{t}$ production cross-section in the lepton+jets channel at $\\sqrt{s}=13\\;$TeV with the ATLAS experiment", "issued": {"date-parts": [["2025", "11", "17"]]}, "abstract": "The $t\\bar{t}$ production cross-section is measured in the lepton+jets channel using proton-proton collision data at a centre-of-mass energy of $\\sqrt{s}=13$ TeV collected with the ATLAS detector at the LHC. 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.", "author": [{"family": " Georges Aad"}, {"family": " Brad Abbott", "uri": "http://orcid.org/"}, {"family": " Dale Charles Abbott", "uri": "http://orcid.org/"}, {"family": " Adam Abed Abud", "uri": "http://orcid.org/"}, {"family": " Kira Abeling", "uri": "http://orcid.org/"}, {"family": " Deshan Kavishka Abhayasinghe", "uri": "http://orcid.org/"}, {"family": " Syed Haider Abidi", "uri": "http://orcid.org/"}, {"family": " Ossama Abouzeid", "uri": "http://orcid.org/"}, {"family": " Nicola Abraham", "uri": "http://orcid.org/"}, {"family": " Halina Abramowicz", "uri": "http://orcid.org/"}], "type": "dataset", "id": "inspirehep_2bb1d880-23a2-455b-82b8-bc547f884d5d", "URL": "https://service.tib.eu/vdataset/inspirehep_2bb1d880-23a2-455b-82b8-bc547f884d5d"}
