Sources of systematic uncertainties for the LS method and their effects on the background prediction in bins of . The full list of systematic uncertainties is given for H _T>750 GeV, and the total uncertainties are shown for H _T>500 GeV and H _T>1000 GeV. Each uncertainty is expressed as a change in the ratio of the predicted to the true number of events (evaluated with simulation). Uncertainties associated with the dilepton and QCD backgrounds are discussed in the text. The total uncertainty is the individual uncertainties summed in quadrature
