Nature of problem:
The W pair production and decay will be used as an important data point for precise tests of the standard electroweak theory at LEP2 and higher energies. The effects due to QED bremsstrahlung and apparatus efficiency have to be subtracted from the data. The program includes also effects of the secondary decays, i.e. hadronization of quarks and tau lepton decays.
The Monte Carlo simulation of the combined W production and decay process including subsequent decays of tau lepton and/or hadronization of quarks is used to calculate the effects of spin and the effects of radiative corrections, including hard bremsstrahlung, simultaneously. Any experimental cut and apparatus efficiency may be introduced easily by rejecting some of the generated events.
Efficiency is about 30 CPU sec. of HP-9000/735/99 per 1000 unweighted events, for the parameter setting as in the demonstration output.
