QCD phase diagram和使用RHIC低能量扫描数据定位临界点

QCD phase diagram and locating critical point using RHIC low energy scan data

Mingmei Xu, Meiling Yu, Lianshou Liu

摘要:

结果表明,RHIC能量扫描实验可以作为研究系统沿一级相变线(即通过临界点的二级相变过程)演化的有效工具。在这个过程中,系统结构在通过临界点时发生了变化,相应地,末态粒子的横动量得到了一个额外的分量。这种现象可以提供有关系统在不同阶段结构的有用信息,并可以作为定位临界点的有效信号。

英文摘要:

It is shown that the RHIC energy-scan experiments can serve as an effective tool for studying the system evolution along the first order phase transition line passing the critical point, which is a second order phase transition process. During this process the system structure changes while passing the critical point, and correspondingly, the transverse momentum of the final state particles gets an extra component. This phenomenon can provide useful information about the system structure in different phases and can serve as an effective signal for locating the critical point.
