dc.description.abstractThe inclusive and fiducial tt ¯ production crosssections are measured in the lepton+jets channel using 20.2 fb−1 of proton–proton collision data at a centre-ofmass energy of 8 TeV recorded with the ATLAS detector at the LHC. Major systematic uncertainties due to the modelling of the jet energy scale and b-tagging efficiency are constrained by separating selected events into three disjoint regions. In order to reduce systematic uncertainties in the most important background, the W+ jets process is modelled using Z+ jets events in a data-driven approach. The inclusive tt ¯ cross-section is measured with a precision of 5.7% to be σinc(tt ¯) = 248.3±0.7 (stat.)±13.4 (syst.)±4.7 (lumi.) pb, assuming a top-quark mass of 172.5 GeV. The result is in agreement with the Standard Model prediction. The crosssection is also measured in a phase space close to that of the selected data. The fiducial cross-section is σfid(tt ¯) = 48.8 ± 0.1 (stat.) ± 2.0 (syst.) ± 0.9 (lumi.) pb with a precision of 4.5%.en_US
