Distribution of (a) the 3-jet solid angle $\Omega$ and (b) the neural network output for the selected hadronic events. The points are data, the hatched histograms represent the background and the open histograms show the expected signal from $\mathrm{e} \nu_\mathrm{e} \q\q$ final states as predicted by the EXCALIBUR Monte Carlo.

The energy spectra of the selected (a) single electron, (b) single muon, and (c) single tau candidates. The sum of the different lepton energy spectra is shown in (d). The points are data, the hatched histograms correspond to the background contribution. The open histograms show the expected signal from $\mathrm{e} \nu_\mathrm{e} \ell \nu_\ell$ final states as predicted by the EXCALIBUR Monte Carlo.

The measured cross-section of single W production within our phase-space cuts as a function of the centre-of-mass energy. The solid and dashed lines show predictions of the GRC4F and EXCALIBUR Monte Carlo programs, respectively. The estimated theoretical uncertainty of $\pm 7\%$ is indicated by the band.
The contours corresponding to 68\% and 95\% confidence level in the $\rm \kappa_\gamma - \rm \lambda_\gamma$ plane. The point indicates the global minimum from the 2-parameter fit, to be compared with the Standard Model prediction indicated by the star.
