Prospects for the Top Pair Production Cross-section at √s = 10TeV in the Single Lepton Channel in ATLAS

This page contains approved plots and results as they appear in the ATL-PHYS-PUB-2009-087 note. Only the note contains all the relevant information and should thus be consulted if one of the plots is used.

Figure 1: Left: Electron reconstruction efficiency versus true pT and, right, versus h.

Figure 2: Left: Muon reconstruction efficiency versus true pT and right, versus h.

Figure 3: Left: Expected distribution of the three-jet invariant mass after the standard selection. Right: The same after the MW-cut. Both plots are for the electron analysis, and the distributions are normalised to 200 pb−1 .

Figure 4: Left: The likelihood fit in the three-jet invariant mass for the electron channel. Right: The same for the muon channel. The statistical uncertainties correspond to an integrated luminosity of 200 pb−1 .

Figure 5: Ratio of reconstructed jet multiplicity for W→ ln+jets over Z→ ll+jets events. The ratio is taken after event selection cuts and normalizing the ratio to the 1 jet bin. Statistical errors are shown.

Figure 6: (Left) Reconstructed top invariant mass distribution for QCD events (passing the hadronic selection only, QCD template) superimposed to W+jets and QCD events (passing the full selection) for the electron channel. (Right) c2 fit to the top invariant mass distribution for the muon channel, normalised to 200 pb−1.
