摘要

本研究试图详细研究在4.5A和14.5A GeV/c入射动量下，si核相互作用中产生的相对论性带电粒子的事件-事件(e-by-e)伪快度波动。本研究中使用的方法利用了一个运动学变量，该变量是根据平均伪速度和单个事件中产生的粒子总数推导出来的。本文还研究了这些波动的多重性和伪快速依赖性。将实验数据与HIJING仿真结果进行了比较。

On Event-by-event Pseudorapidity Fluctuations in Relativistic Nuclear Interactions

Present study is an attempt to have a detailed look into event-by-event(e-by-e) pseudorapidity fluctuations of the relativistic charged particles produced in $^{28}$Si-nucleus interactions at incident momenta 4.5A and 14.5A GeV/c.The method used in the present study makes use of a kinematic variable which is derived in terms of the average pseudo-rapidity and the total number of particles produced in a single event. The multiplicity and pseudorapidity dependence of these fluctuations have also been studied. The results obtained for the experimental data are compared with HIJING simulation.
