| 英文摘要 | A measurement is presented of the (tt) over bar inclusive production cross section in pp collisions at a center-ofmass energy of pffisffiffi root s = 8 tev using data collected by the atlas detector at the cern large hadron collider. the measurement was performed in the lepton + jets final state using a data set corresponding to an integrated luminosity of 20.3 fb(-1). the cross section was obtained using a likelihood discriminant fit and b-jet identification was used to improve the signal-to-background ratio. the inclusive (tt) over bar production cross section was measured to be 260 +/- 1(stat)(-23)(+22)(stat) +/- 8(lumi) +/- 4(beam) pb assuming a top-quark mass of 172.5 gev, in good agreement with the theoretical prediction of 253(-15)(+13) pb. the (tt) over bar -> (e, mu) + jets production cross section in the fiducial region determined by the detector acceptance is also reported. |
