Predicted and observed distributions of the lepton centrality (
top) and the minimum centrality of additional jets (
bottom) for events in the inclusive fiducial region (i.e. after preselection) in 7



(
left) and 8



(
right) data. The
arrows in the lepton-centrality distributions separate the signal-region selection (to the
left) from the control-region selection (to the
right). The
arrows in the jet-centrality distributions separate the signal-region selection (to the
right) from the validation-region selection (to the
left). The
bottom panel in each distribution shows the ratio of data to the prediction. The
shaded band represents the statistical and experimental uncertainties summed in quadrature
