相对论重离子碰撞中单事件阶乘矩的分析

论述了在相对论重离子碰撞中进行单事件分析的必要性．采用随机级联模型对相对论性核－核碰撞进行ＭｏｎｔｅＣａｒｌｏ模拟，通过对核－核碰撞单事件样本阶乘矩ｌｎＦ２ｓ－ｌｎＭ曲线的分析，得出了单事件的ｌｎＦ２ｓ－ｌｎＭ曲线上翘，且上翘程度随碰撞核基元碰撞数Ａ的增加而加剧的结论，并讨论了这一结果可能作为ＱＧＰ物质形成信号的意义

ANALYSIS OF SINGLE EVENT FACTORIAL MOMENT IN RELATIVISTIC HEAVY ION COLLISION

The necessity to conduct single event analysis for relativistic heauy ion collision is commented.By Monte Carlo simulation and analysis of the curve ln F 2s -ln M of relativistic nucleus-nucleus collision,It is found that the curve bends upward and the bending extent increases with the increases of nucleus collision number A.This observation may be a significant sign for the formation of QGP matter.
