Measurement of the top quark pair production cross section in dilepton final states with ATLAS

The production cross section of top quark pairs in proton-proton (pp) collisions at √s = 7 TeV recorded with the ATLAS detector at the CERN Large Hadron Collider is measured. Using a data sample of 35 pb−1, candidate events are selected in the dilepton topology with large missing transverse energy (...

Sumario:The production cross section of top quark pairs in proton-proton (pp) collisions at √s = 7 TeV recorded with the ATLAS detector at the CERN Large Hadron Collider is measured. Using a data sample of 35 pb−1, candidate events are selected in the dilepton topology with large missing transverse energy (ETmiss) and at least two jets. Backgrounds from Zll and mis-identified leptons (fakes) are estimated from data. Results include detailed studies of systematic uncertainties.
