A detailed study of event-by-event fluctuations of maximum particle density of the produced particles with respect to the width of the pseudo-rapidity interval in terms of the scaled variance ω has been carried out for 16 O-AgBr, 28 Si-AgBr and 32 S-AgBr interactions at 4.5 A GeV/ c . For all the interactions the values of scaled variance are found to be greater than one indicating the presence of strong event-by-event fluctuations of maximum particle density values in the multiparticle production process. The event-by-event fluctuations are found to decrease with the increase of the width of the pseudo-rapidity interval. Experimental analysis has been compared with the results obtained from the analysis of events simulated by generating random numbers (MC-RAND) and the Ultra-Relativistic Quantum Molecular Dynamics (UrQMD) model. MC-RAND events show significantly less event-by-event fluctuations in comparison to the experimental data. Th...

在几A GeV / c下，最大粒子密度相对于伪快速区间宽度的逐事件波动

对于16 O-AgBr，28 Si-AgBr，已对按比例方差ω产生的最大颗粒密度随伪快速区间宽度的逐事件波动进行了详细研究。在32 A GeV / c下有32和S-AgBr相互作用。对于所有相互作用，发现比例变化值大于1，表明在多颗粒生产过程中存在最大颗粒密度值的逐事件强烈波动。发现事件之间的波动随着伪快速间隔的宽度的增加而减小。将实验分析与通过生成随机数（MC-RAND）和超相对论量子分子动力学（UrQMD）模型模拟​​的事件分析获得的结果进行了比较。与实验数据相比，MC-RAND事件显示逐个事件的波动要小得多。那个...
