Data-driven Determination of Standard Model Background to Supersymmetry Searches in ATLAS — •Vadym Zhuravlov, Hubert Kroha, Federica Legger, and Xu Ai Zhuang — Max-Planck-Institut für Physik, Munich, Germany

The Standard Model tt production process belongs to the most important backgrounds to searches for Supersymmetry at the Large Hadron Collider at CERN. We describe methods to measure this background in events with large missing transverse energy, multi-jets and 0, 1 or 2 leptons with the first data of ATLAS experiment.
