Abstract.

Existence of discrepancies between experimental data and Monte Carlo predictions for angular distributions in four-jet production via \(e^+e^-\) annihilation has been known for some time at LEP1. As such QCD processes constitute significant backgrounds to \(e^+e^-\to W^+W^- \to 4\)-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 \(W^\pm\) boson parameters.
