Top quark pair production Cross Section in ATLAS with early data
A search is performed for top quark pairs with early data of ATLAS pp collision taken at √s = 7 TeV. Several candidate events are observed, in both lepton plus jets and dilepton channels. The properties of these events are described, and compared to the expectations from Monte Carlo simulation. A fi...

| Sumario: | A search is performed for top quark pairs with early data of ATLAS pp collision taken at √s = 7 TeV. Several candidate events are observed, in both lepton plus jets and dilepton channels. The properties of these events are described, and compared to the expectations from Monte Carlo simulation. A first study of the backgrounds in the lepton plus jets channel is presented including a data-driven determination of the contribution of QCD multi-jet events. |
