Description

The matrix element for single hard photon bremsstrahlung in the dominant LEP II process e+e- → W+W- → 4f with massless fermions is given. An appropriate Monte Carlo event generator is described and the results for total cross sections and the photon spectrum are presented. The narrow width approximation for the W and the background are discussed. (orig.)
