Measurement of the top-quark pair production cross-section at the ATLAS experiment with a kinematic fit — •Moritz Bunse and Florian Hirsch — TU Dortmund, Fak. Physik, E4
Since March 2010 the LHC is providing proton-proton collisions at 7 TeV center-of-mass energy for the ATLAS experiment. A method to extract the top-pair production cross-section in the single-lepton channel from the lepton eta distribution and its application to the 35 pb−1 of collected data is presented.
