论文摘要
在本文中，我们研究了在高能核碰撞中观察到的带电颗粒的多样性波动，并将其与在此类过程中发生的强调系统的大小相关联。我们使用平均倍增性$ \ langle n \ rangle $和差异$ var \ left（n \右）$的多重分布的中心性粒子的多重分布选择了相对论重型离子核的选择碰撞，以评估动态变量$ω$并研究其碰撞核核量的依赖性。我们将观察到的系统大小波动的依赖性与聚类现象以及强调源的有限性和热浴之间联系起来。
In this paper, we investigate the multiplicity fluctuations of charged particles observed in high-energy nuclear collisions and relate them to the size of hadronizing systems which happen during such processes. We use the average multiplicities $\langle N\rangle $ and variances $Var\left(N\right)$ of multiplicity distributions of charged particles produced in centrality selected collisions of relativistic heavy-ion nuclei to evaluate the dynamic variable $Ω$ and study its dependence on the size of colliding nuclei. We connect the observed system-size dependence of multiplicity fluctuations with the clustering phenomena and the finiteness of the hadronizing sources and the thermal bath.
