Query: Effects of Perturbative Colour Interference on WW -> 6-jet Distributions   At LEP II it is hoped to measure the W mass to an accuracy of around 40 MeV.
This will require direct reconstruction of the mass of the W from its decay
products in both the semi-leptonic and hadronic decay channels. Final state
perturbative reconnection effects in hadronic decays are considered and their
effect on 6-jet distributions and the reconstructed mass. The perturbative mass
shift is found to be ~ 50 keV in the negative direction.
