Measurement of the tt¯ production cross-section in pp collisions at √s = 5.02 TeV with the ATLAS detector
Original language description
The inclusive top-quark pair (tt‾tt) production cross-section σtt‾σtt is measured in proton–proton collisions at a centre-of-mass energy √s = 5.02 TeV, using 257 pb−1−1 of data collected in 2017 by the ATLAS experiment at the LHC. The tt‾tt cross-section is measured in both the dilepton and single-lepton final states of the tt‾tt system and then combined. The combination of the two measurements yieldsσtt‾=67.5±0.9(stat.)±2.3(syst.)±1.1(lumi.)±0.2(beam)pb,σtt=67.5±0.9(stat.)±2.3(syst.)±1.1(lumi.)±0.2(beam)pb,where the four uncertainties reflect the limited size of the data sample, experimental and theoretical systematic effects, and imperfect knowledge of both the integrated luminosity and the LHC beam energy, giving a total uncertainty of 3.9%.
