Bose-Einstein Correlations in WW Events at LEP2

Abstract

Analyses of Bose-Einstein Correlations in ${\text{rW}}^{+}{\text{rW}}^{-}$ events at LEP2 by the four LEP collaborations are presented. In particular, Bose-Einstein correlations in ${\text{rW}}^{+}{\text{rW}}^{-}$ overlap are investigated and the possible existence of these correlations between particles coming from different W's, which may influence the W-mass measurements in the fully hadronic channel \re^{+}\re^{-}\to \rW^{+}\rW^{-}\to\rq_1 \bar{\rq}_2 \rq_3 \bar{\rq}_4 . No evidence for such an inter-W Bose-Einstein correlation is found. The results are preliminary.
