Measurement of the tt(bar) production cross-section in pp collisions at CMS = 5.02 TeV with the ATLAS detector
Original language description
The inclusive top-quark pair (t-t) production cross-section t-t is measured inproton-proton collisions at a centre-of-mass energy ps = 5.02TeV, using 257 pb-1 of datacollected in 2017 by the ATLAS experiment at the LHC. The t-t cross-section is measuredin both the dilepton and single-lepton final states of the t-t system and then combined. Thecombination of the two measurements yieldst-t = 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 andtheoretical systematic effects, and imperfect knowledge of both the integrated luminosityand the LHC beam energy, giving a total uncertainty of 3.9%. The result is in agreementwith theoretical quantum chromodynamic calculations at next-to-next-to-leading order inthe strong coupling constant, including the resummation of next-to-next-to-leading logarithmicsoft-gluon terms, and constrains the parton distribution functions of the proton atlarge Bjorken-x.
