Measurement of Bose-Einstein Correlations in e+e- -> W+W- Events at LEP
Abstract
Bose-Einstein correlations in W-pair production at LEP are investigated in a data sample of 629 pb-1 collected by the L3 detector at centre-of-mass energies of 189-209 GeV. Bose-Einstein correlations between pions within a W decay are observed and found to be in good agreement with those in light-quark Z decay. No evidence is found for Bose-Einstein correlations between hadrons coming from different W's in the same event.
