Background studies for top-pair production in lepton plus jets final states in $\sqrt{s}=7 TeV$ ATLAS data

The search for top quark pairs at the LHC requires the selection of events with leptons, high jet multiplicity, b-tagged jets and missing transverse energy, and the study of control samples with lower jet multiplicity to evaluate the backgrounds. A first study of the backgrounds in the lepton plus j...

description The search for top quark pairs at the LHC requires the selection of events with leptons, high jet multiplicity, b-tagged jets and missing transverse energy, and the study of control samples with lower jet multiplicity to evaluate the backgrounds. A first study of the backgrounds in the lepton plus jets channel is presented using 295 nb^-1 of ATLAS pp collision data taken at 7 TeV, including a data-driven determination of the contribution QCD multi-jet events.
