论文摘要
高能核冲突实验的最终目标之一是映射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阶段结构，包括搜索关键行为以及验证一阶相变点的临界终点的可能存在。探测临界行为的有前途的工具是研究保守电荷的波动和相关性，因为在热系统中，这些波动与研究系统的状态（EOS）方程直接相关。在本报告中，概述了对Net-Proton多重性分布（例如累积和多粒子相关函数）的几个实验测量。
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.
