利用LEP的Aleph探测器在e+e−质心能量从183GeV到209GeV收集的数据，研究了W对衰变中的玻色-爱因斯坦关联。该分析基于WW→QQ QQ事件与由WW→QQℓν事件的强子部分构建的“混合”事件的比较。这些数据与玻色-爱因斯坦关联只存在于来自相同W衰变的介子的假设是一致的。具有来自不同W玻色子的介子之间的玻色-爱因斯坦关联的喷口模型是不受欢迎的。
Bose–Einstein correlations in W-pair decays are studied using data collected by the ALEPH detector at LEP at e+e−centre-of-mass energies from 183 to 209 GeV. The analysis is based on the comparison of WW→qq¯qq¯ events to “mixed” events constructed with the hadronic part of WW→qq¯ℓν events. The data are in agreement with the hypothesis that Bose–Einstein correlations are present only for pions from the same W decay. The JETSET model with Bose–Einstein correlations between pions from different W bosons is disfavoured.
