Bose-Einstein and colour interference in W-pair decays

Häkkinen, Jari LU and Ringnér, Markus LU (1998) In European Physical Journal C. Particles and Fields 5(2). p.275-281
Abstract
We study effects on the W mass measurements at LEP2 from non-perturbative interference effects in the fully hadronic decay channel. Based on a model for Bose-Einstein interference, which is in agreement with LEP1 data, we argue that there are no Bose-Einstein correlations between bosons coming from the different W's. For small reconnection probabilities we rule out the possible experimental signal of colour interference at LEP2, suggested in [1]. The conclusions from this paper are that the theoretical uncertainties in the W mass determination should be smaller than the experimental statistical error.
