摘要
Existence of discrepancies between experimental data and Monte Carlo predictions for angular distributions in four-jet production via annihilation has been known for some time at LEP1. As such QCD processes constitute significant backgrounds to -jet production at LEP2, we consider the possibility that an erroneous modelling of the helicity structure of the final-state partons could affect the accuracy of experimental measurements of the boson parameters
