This measurement uses events with an opposite-charge electron--muon pair in the final state. Jets containing $b$-quarks are tagged using an algorithm based on track impact parameters and reconstructed secondary vertices. The numbers of events with exactly one and exactly two $b$-tagged jets are counted and used to determine simultaneously $\\sigma_{t\\bar{t}}$ and the efficiency to reconstruct and $b$-tag a jet from a top quark decay, thereby minimising the associated systematic uncertainties. The cross-section is measured to be: $\\sigma_{t\\bar{t}}$= 818 $\\pm$ 8 (stat) $\\pm$ 27 (syst) $\\pm$ 19 (lumi) $\\pm$ 12 (beam) pb, where the four uncertainties arise from data statistics, experimental and theoretical systematic effects, the integrated luminosity and the LHC beam energy, giving a total relative uncertainty of 4.4%. The result is consistent with theoretical QCD calculations at next-to-next-to-leading order. A fiducial measurement corresponding to the experimental acceptance of the leptons is also presented.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.73120.v1/t1","@type":"Dataset","description":"Measured cross-section for $t\\bar{t}$ events using $e\\mu$ events with b-tagged jets in pp collisions at $\\sqrt{s}$=13 TeV.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.73120.v1/t2","@type":"Dataset","description":"Measured fiducial cross-section for $t\\bar{t}$ events producing an $e\\mu$ pair, each lepton originating directly from t $\\rightarrow$ W $\\rightarrow$ l...","name":"Table 2"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1468168?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/73120"}],"inLanguage":"en","name":"Measurement of the $t\\bar{t}$ production cross-section using $e\\mu$ events with b-tagged jets in pp collisions at $\\sqrt{s}$=13 TeV with the ATLAS detector","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1468168?version=1","version":1}
