Remarks:

efficiencies and background take into account inefficiencies due to beam related background in the lvlv channel

numbers in parentheses are standard model predictions for Mw=80.39 GeV/c2 and Xecm=188.6 GeV, the leptonic BR is 10.83%, thus the hadronic Br is 45.58%

Below are the NN14 output, y34 and the 14 input distributions of the NN after preselection. Data are black dots. MC is normalized to the quoted luminosity (shaded area is the total background including non-4q events. A binned log likelihood fit over the whole range of the distribution is depicted by the smooth black line. Results are given at the top of each figure. Last plots show the variation of the cross section obtained for each distribution with the standard 1 parameter fit.
