Book Description
A measurement of the t$ar{t}$ production cross section in the lepton+jets channels with the D0 detector at √s = 1.96 TeV using the lifetime-tagging techniques is presented. The t$ar{t}$ cross section is estimated from the combination of the e+jets and ?+jets channels. The obtained result ?t$ar{t}$ = 7.47$+ 1.22top{-1.14}$(stat)$+ 1.65top{-1.03}$(syst) ± 0.49(lumi) pb is consistent with the Standard Model expectation.
