利用OPAL探测器1991 - 1995年LEP 1观测到的Z 0衰变中的两个连续喷注强子事例，观测到π 0对中的玻色-爱因斯坦关联。用静态高斯图象得到π介子发射源的混沌参数λ=0.55±0.10±0.10，源半径R=（0.59±0.08±0.05）fm。根据JETSET和HERWIG Monte Carlo模型，我们的数据样本中的玻色-爱因斯坦关联在很大程度上将来自不同强子衰变的π 0联系起来。在弦分裂或团簇衰变时形成的瞬发π介子只占样品的一小部分。
We observe Bose–Einstein correlations in π0pairs using back-to-back two jet hadronic events from Z0decays in the data sample collected by the OPAL detector at LEP 1 from 1991 to 1995. Using a static Gaussian picture for the pion emitter source, we obtain the chaoticity parameter λ=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 π0s 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.
