摘要

研究表明，阶乘矩分析依赖于相空间单元的大小（当后者减小但仍然相当大时），它对位于二维单元中的系统内的粒子束化非常敏感。根据最近在 RHIC/STAR 的 sNN = 7.7 到 200 GeV 的不同能量范围内观察到的中心 Au + Au 对撞中电荷粒子密度波动的发现，建议分析相对论重离子对撞中的因子矩可以作为研究与相关现象有关的密度波动的一种方法。通过使用阶乘矩分析来获取其中包含的新信息，可能会丰富我们对粒子产生机制的理解，而这些新信息是四十年前通过观察 "尖峰 "现象获得的。

Probing multi-particle bunching from intermittency analysis in relativistic heavy-ion collisions

It has been demonstrated that factorial moments analysis in dependence on the size of phase-space cells (when the latter is decreased but is still considerably large) exhibits sensitivity to particle bunching within a system situated in the two-dimensional cell. Based on recent findings concerning fluctuations in charge particle density observed in central Au + Au collisions at various energies ranging from

\sqrt{s_{N N}}

= 7.7 to 200 GeV at RHIC/STAR, it is proposed that analyzing factorial moments in relativistic heavy-ion collisions could serve as a method to investigate density fluctuations linked to correlation phenomena. Our understanding of particle production mechanisms may be enriched by using factorial moments analysis to gain new information contained in them that was initiated four decades ago from observation of “spike” phenomena.
