Events are selected if they contain a single lepton (electron or muon) or an opposite-sign lepton pair, in association with multiple jets. The events are categorised according to the number of jets and how likely these are to contain b-hadrons. A multivariate technique is then used to discriminate between signal and background events. The measured four-top-quark production cross section is found to be 26+17−15 fb, with a corresponding observed (expected) significance of 1.9 (1.0) standard deviations over the background-only hypothesis. The result is combined with the previous measurement performed by the ATLAS Collaboration in the multilepton final state. The combined four-top-quark production cross section is measured to be 24+7−6 fb, with a corresponding observed (expected) signal significance of 4.7 (2.6) standard deviations over the background-only predictions. It is consistent within 2.0 standard deviations with the Standard Model expectation of 12.0 ± 2.4 fb."],["dc.identifier.citation","Journal of High Energy Physics. 2021 Nov 16;2021(11):118"],["dc.identifier.doi","10.1007/JHEP11(2021)118"],["dc.identifier.pii","17160"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/97976"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/112858"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-507"],["dc.publisher","Springer Berlin Heidelberg"],["dc.relation.eissn","1029-8479"],["dc.rights.holder","The Author(s)"],["dc.subject","Hadron-Hadron scattering (experiments)"],["dc.subject","Top physics"],["dc.title","Measurement of the t$t\\overline{t}t\\overline{t}$ production cross section in $\\mathit{pp}$ collisions at √s = 13 TeV with the ATLAS detector"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
