Measurement of the tt production cross-section and lepton differential distributions in eμ dilepton events from pp collisions at √ s = 13 TeV with the ATLAS detector Aad, G. Aguilar Saavedra, Juan Antonio Atlas Collaboration The inclusive top quark pair (t ¯t) production cross-section σt ¯t has been measured in proton–proton collisions at √ s = 13 TeV, using 36.1fb−1 of data collected in 2015–2016 by the ATLAS experiment at the LHC. Using events with an opposite-charge eμ pair and b-tagged jets, the cross-section is measured to be: σt ¯t = 826.4 ± 3.6 (stat) ± 11.5 (syst) ± 15.7 (lumi) ±1.9 (beam) pb, where the uncertainties reflect the limited size of the data sample, experimental and theoretical systematic effects, the integrated luminosity, and the LHC beam energy, giving a total uncertainty of 2.4%. The result is consistent with theoretical QCD calculations at next-to-next-to-leading order. It is used to determine the top quark pole mass via the dependence of the predicted cross-section on mpole t , giving mpole t = 173.1+2.0 −2.1 GeV. It is also combined with measurements at √ s = 7 TeV and √ s = 8 TeV to derive ratios and double ratios of t ¯t and Z cross-sections at different energies. The same event sample is used to measure absolute and normalised differential cross-sections as functions of singlelepton and dilepton kinematic variables, and the results are compared with predictions from various Monte Carlo event generators. 2020-11-27T10:32:05Z 2020-11-27T10:32:05Z 2020-06-12 info:eu-repo/semantics/article ATLAS Collaboration., Aad, G., Abbott, B. et al.
