Abstract
Bose-Einstein correlations between like-sign charged-particle pairs in e + e − → W + W − events recorded with the OPAL detector at LEP at centre-of-mass energies between 183 GeV and 209 eV are studied. Test variables are used to investigate the presence of correlations between hadrons originating from different W bosons in W + W − → qq events. Within the statistics of the data sample no evidence for inter-WW Bose-Einstein correlations is obtained. The data are also compared with predictions'of a recent implementation of Bose-Einstein correlation effects in the Monte Carlo model PYTHIA. This presentation is based on [1].
