Prospects for Measuring Top Pair Production in the di-lepton Channel with early ATLAS Data at √s = 10TeV

This page contains approved plots and results as they appear in the ATL-PHYS-PUB-2009-086 note. Only the note contains all the relevant information and should thus be consulted if one of the plots is used.

Figure 1: Electron trigger efficiency as a function of pT (on the left) and η (on the right) for the signal events. The shaded area shows the pT and η distributions of reconstructed electrons that match true electrons from W decays. The efficiencies are measured with respect to the offline event selection (Section 2.2).

Figure 2: Electron reconstruction efficiencies as a function of electron pT (left) and η (right) for signal events as predicted from the simulation. The shaded area shows the pT and η distributions of true electrons from W decays.

Figure 3: Muon reconstruction efficiencies as a function of muon pT (left) and η (right) for signal events as predicted from the simulation. The shaded area shows the pT and η distributions of true muons from W decays.
