波动和相关性测量概述

Overview of fluctuation and correlation measurements

Anar Rustamov

摘要:

高能核碰撞实验的最终目标之一是绘制强相互作用物质的相图。一个非常具有挑战性的任务是确定QCD相结构,包括寻找临界行为和验证一阶相变线的临界端点的可能存在。一个有前途的工具,以探测临界行为的存在是研究的波动和相关性的保守电荷,因为在热系统中,这些波动是直接相关的状态方程(EoS)的系统下的研究。在这份报告中,给出了一个概述的几个实验测量净质子多重数分布,如累积量和多粒子关联函数。

英文摘要:

One of the ultimate goals of nuclear collision experiments at high energy is to map the phase diagram of strongly interacting matter. A very challenging task is the determination of the QCD phase structure including the search for critical behavior and verification of the possible existence of a critical end point of a first order phase transition line. A promising tool to probe the presence of critical behavior is the study of fluctuations and correlations of conserved charges since, in a thermal system, these fluctuations are directly related to the equation of state (EoS) of the system under the study. In this report an overview is given of several experimental measurements on net-proton multiplicity distributions such as cumulants and multi-particle correlation functions.
