Abstract
We observe Bose-Einstein correlations in pi(0) pairs using back-to-back two jet hadronic events from Z(0) decays in the data sample collected by the OPAL detector at LEP I from 101 to 1995. Using a static Gaussian picture for the pion emitter source, we obtain the chaoticity parameter lambda = 0.55 +/- 0.10 +/- 0.10 and the source radius R = (0.59 +/- 0.08 +/- 0.05) fm. According to the JETSET and HERWIG Monte Carlo models, the Bose-Einstein correlations in our data sample largely connect pi(0)s originating from the decays of different hadrons. Prompt pions formed at string break-ups or cluster decays only form a small fraction of the sample. (C) 2003 Elsevier Science B.V. All rights reserved.
