Measurement of the cross section for top-quark pair production in pp collisions at sqrt{s} = 7 TeV with the ATLAS detector using final states with two high-pT leptons
Original language description
A measurement is reported of the production cross section of top-quark pairs in proton-proton collisions at a center-of-mass energy of 7 TeV recorded with the ATLAS detector at the LHC. Candidate events have a signature consistent with containing two isolated leptons, large missing transverse momentum, and at least two jets. Using a data sample corresponding to an integrated luminosity of 0.70 fb^-1, a t-tbar production cross section sigmattbar=176 +/-5 (stat) +14 -11 (syst) +/- 8 (lum.) pb is measuredfor an assumed top-quark mass of m_t = 172.5 GeV.
