几个AGeV/c粒子最大密度在窄赝快度区间的逐事件涨落
Event-By-Event Fluctuation of Maximum Particle Density in Narrow Pseudo-Rapidity Interval at a Few AGeV/c
摘要：
在入射动量为4.5AGeV/c时，对16 O-AgBr，28 Si-AgBr和32 S-AgBr相互作用中产生粒子的最大粒子密度在窄赝快度区间内随标度方差ω的逐事件涨落进行了详细的研究。对于所有的相互作用的缩放方差的值被发现是大于零，表明存在强烈的事件由事件波动的最大粒子密度值在多粒子生产过程中。随赝快度间隔的增大，事件涨落减小。实验分析结果与超相对论量子分子动力学（UrQMD）模型模拟事件的分析结果进行了比较。UrQMD模型不能重复实验结果。
英文摘要：
A detailed study of event by event fluctuation of maximum particle density of the produced particles in narrow pseudo-rapidity interval in terms of the scaled variance ω has been carried out for 16O-AgBr, 28Si-AgBr and 32S-AgBr interactions at an incident momentum of 4.5 AGeV/c. For all the interactions the values of scaled variance are found to be greater than zero indicating the presence of strong event by event fluctuation of maximum particle density values in the multiparticle production process. The event by event fluctuations are found to decrease with the increase of pseudo-rapidity interval. Experimental analysis has been compared with the results obtained from the analysis of events simulated by the Ultra Relativistic Quantum Molecular Dynamics (UrQMD) model. UrQMD model could not replicate the experimental results.
