Measurement of tt‾ production in association with additional b-jets in the eμ final state in proton–proton collisions at √s= 13 TeV with the ATLAS detector
Original language description
This paper presents measurements of top-antitop quark pair (tt‾tt) production in association with additional b-jets. The analysis utilises 140 fb−1 of proton–proton collision data collected with the ATLAS detector at the Large Hadron Collider at a centre-of-mass energy of 13 TeV. Fiducial cross-sections are extracted in a final state featuring one electron and one muon, with at least three or four b-jets. Results are presented at the particle level for both integrated cross-sections and normalised differential cross-sections, as functions of global event properties, jet kinematics, and b-jet pair properties. Observable quantities characterising b-jets originating from the top quark decay and additional b-jets are also measured at the particle level, after correcting for detector effects. The measured integrated fiducial cross-sections are consistent with tt‾bb‾ predictions from various next-to-leading-order matrix element calculations matched to a parton shower within the uncertainties of the predictions.
