论文摘要
通过在狭窄的伪长度间隔中，在16o-agbr，28si-agbr和32S-Agbr相互作用的入射动量为4.5 ageV/c时，对事件的最大颗粒密度在狭窄的伪长度间隔中的最大颗粒密度进行了详细研究。对于所有相互作用，发现缩放方差的值大于零，表明存在强度事件，这是由于多颗粒生产过程中最大粒子密度值的事件波动而存在的。发现随事件波动的事件随着伪长度间隔的增加而减少。已经将实验分析与通过超级量子分子动力学（URQMD）模型模拟的事件分析获得的结果进行了比较。 URQMD模型无法复制实验结果。
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.
