每个核子 200 GeV/c 下硫-铅碰撞的 π+π+π+ 相关性通过 CERN 实验 NA44 的聚焦光谱仪测量得到。我们研究了中速的三π介子相关函数，发现真正的三体相关性被抑制了。对该结果的可能解释是粒子的发射是部分相干的。
π+π+π+correlations from sulphur-lead collisions at 200 GeV/c per nucleon are presented as measured by the focusing spectrometer of experiment NA44 at CERN. We have investigated the three-pion correlation function at mid-rapidity and found that a genuine three-body correlation is suppressed. A possible interpretation of this result is that the emission of particles is partially coherent.
