Nature of problem:
Higher order leading logarithmic QED radiative corrections to W pair production and decay at high energy e+e- colliders, including finite width of the W's.
Monte Carlo event generation.
The matrix elements for the hard subprocess contain only the resonant contributions to e+e- -> (W+W-) -> 4 fermions in the Born approximation. The final state fermions from the W decays are generated at the parton level.
Approx 1 ms/event, depending on the energy and cuts. The test run at LEP 200 energies took approximately 19 CPU seconds on an IBM RS/6000-520 running AIX, and 11 CPU seconds on an IBM 3090 running MVS.
