Distributions of the dilepton invariant mass in the WZ candidate events in 7 (top) and 8 (bottom) data. Points represent data and the shaded histograms represent the WZ signal and the background processes. The contribution from nonprompt leptons, dominated by the and Z+jets production, is obtained from data control samples. The contribution from all other backgrounds, labeled ‘MC background’, as well as the signal contribution are determined from simulation
