摘要：

Recently the DELPHI Collaboration reported new data on Bose-Einstein correlations (BECs) measured in e(+) e(-) --> W+ W- events. Apparently no enhancement has been observed. We analyze these data including final state interactions (FSIs) of both Coulomb and strong (s-wave) origin and find that there is an enhancement in BECs but it is overshadowed by the FSIs which are extremely important for those events. We find the following values for the size of the interaction range beta and the degree of coherence lambda: beta=0.87+/-0.31 fm and lambda=1.19+/-0.48, respectively. [S0556-2821(98)08721-9].
