Abstract: The search for first top-quark pair candidate events and the relatedbackground studies using data-driven techniques are reported for about 300inverse nb of 7 TeV proton-proton collision data delivered by the Large HadronCollider LHC and collected with the ATLAS detector. Selected events arecharacterized by the presence of high-pT isolated charged leptons, high jetmultiplicity, jets identified as originating from b-quark by a secondaryvertex tagger algorithm, and missing transverse energy. They reveal kinematicsproperties consistent with top pair production.
