Description

This poster presents the measurement of the inclusive top-quark pair-production cross-section in the lepton+jets channel with 20.2 fb-1 of 8 TeV data collected with the ATLAS detector at the LHC, using a neural-network discriminant and the reconstructed mass of the hadronically decaying W boson. Events are selected by requiring at least four jets, where at least one of the jets is required to be b-tagged. Signal events from the ttbar processes are separated using a neural-network discriminant based on final-state observables. The ttbar production cross-section is obtained from a binned maximum-likelihood fit to the neural-network discriminant and the reconstructed mass of the hadronically decaying W boson. The inclusive ttbar cross-section is measured to be consistent with the Standard Model prediction.
