摘要
利用LEBC泡室照片对400GeV/c pp碰撞产生的带电粒子赝快度分布进行了测量。研究了固定多重数时的两粒子赝快度关联。用结团模型对实验数据进行了拟合,得到的结团平均大小以及结团的衰变宽度随带电粒子多重数的变化不大。
The pseudorapidity distributions of charged particles produced in pp collisions at 400GeV/c have been measured using LEBC films. Two-particle pseudorapidity correlations at fixed multiplicity have been studied. The experimental data was fitted by cluster model. It is found that the average cluster multiplicities as well as the cluster decay widths both vary slightly with charged multiplicity.
