Top Quark Production Measurements at ATLAS

An overview of top quark production measurements using the ATLAS detector at the LHC is presented. Using 35 pb^-1 of data, we measured the ttbar cross-section in the lepton+jets channel to 13% precision and set limits on the cross-section for the all hadronic decay channel. The measurement in the di...

description An overview of top quark production measurements using the ATLAS detector at the LHC is presented. Using 35 pb^-1 of data, we measured the ttbar cross-section in the lepton+jets channel to 13% precision and set limits on the cross-section for the all hadronic decay channel. The measurement in the dilepton channel was performed using 0.70 fb^-1 of data and was combined with the lepton+jets channel result for our most precise ttbar cross-section measurement of \sigma(ttbar+X) =176 +- 5(stat) +13 -10 (syst) +-7(lumi). Single top production was also measured in the t-channel using 0.70 fb^-1 of data.

Using 35 pb−1 of data, we measured the tt̄ cross-section in the lepton+jets channel to 13% precision and set limits on the cross-section for the all hadronic decay channel[1, 2]. The measurement in the dilepton channel was performed using 0.70 fb−1 of data and was combined with the lepton+jets channel result for our most precise tt̄ cross-section measurement of σpp→tt̄+X = 176±5 (stat)+13−10 (syst)±7 (lumi)[3,4].
