摘要

在超相对论重离子碰撞中，夸克和胶子形成了一个强相互作用的复杂系统。通过研究作为各种参数函数的归一化因子矩（Fq），可以揭示在这些碰撞中形成的系统的性质和多粒子产生的机制。据观察，Fq 矩对动态波动的存在很敏感。此外，通过使用玩具模型事件研究这些矩的弹性，可以发现它们对数据测量中的均匀效率具有稳健性。

Normalized factorial moments of spatial distributions of particles in high multiplicity events: A Toy model study

In ultra-relativistic heavy-ion collisions a strongly interacting complex system of quarks and gluons is formed. The nature of the system so created and the mechanism of multi-particle production in these collisions may be revealed by studying the normalized factorial moments (

F_{q}

) as function of various parameters.

F_{q}

moments are observed to be sensitive to the presence of dynamical fluctuations. Further, the resilience of these moments, studied using Toy model events, shows their robustness against the uniform efficiency in the data measurements.
