Inclusive and differential cross-sections for dilepton tt¯ production measured in √s = 13 TeV pp collisions with the ATLAS detector : = Inclusive and differential cross-sections for dilepton tt¯ production measured in [square root]s = 13 TeV pp collisions with the ATLAS detector

Abstract: Differential and double-differential distributions of kinematic variables of leptons from decays of top-quark pairs (tt¯) are measured using the full LHC Run 2 data sample collected with the ATLAS detector. The data were collected at a pp collision energy of √ s = 13 TeV and correspond to an integrated luminosity of 140 fb−1 . The measurements use events containing an oppositely charged eµ pair and b-tagged jets. The results are compared with predictions from several Monte Carlo generators. While no prediction is found to be consistent with all distributions, a better agreement with measurements of the lepton pT distributions is obtained by reweighting the tt¯sample so as to reproduce the topquark pT distribution from an NNLO calculation. The inclusive top-quark pair production cross-section is measured as well, both in a fiducial region and in the full phase-space. The total inclusive cross-section is found to be
