Top quark pair to dilepton cross-section using template fits to jet inclusive dilepton data

We present an ATLAS analysis which aims to minimize systematic uncertainties, in particular the uncertainty on jet energy scale and the dependence on absolute cross-sections for the background, in the measurement of top quark pair to dilepton cross-section. The analysis uses Monte Carlo generated te...

description We present an ATLAS analysis which aims to minimize systematic uncertainties, in particular the uncertainty on jet energy scale and the dependence on absolute cross-sections for the background, in the measurement of top quark pair to dilepton cross-section. The analysis uses Monte Carlo generated templates for the top signal and for the leading backgrounds. These template are fitted to data in the three lepton channels electron-muon, electron-electron and muon-muon. The expected performance on early LHC data is evaluated using pseudo experiments.
