冻结面上的静态临界涨落

Static critical fluctuations on the freeze-out surface

Lijia Jiang, Pengfei Li, Huichao Song

摘要:

在这一过程中,我们总结了我们最近的论文的主要结果,该论文将冻结方案引入到QCD临界点附近的动力学模型中。在这样的静态临界涨落框架内,可以粗略地描述不同$p_T$范围内的净质子的$C_4$和$κσ^2$的束能量扫描(BES)数据。此外,在较低的碰撞能量下,高累积量的动量接受依赖性也可以定性描述。然而,由于正的静态临界波动,$C_2$和$C_3$总是被过度预测。

英文摘要:

In this proceeding, we summarize the main results of our recent paper, which introduces a freeze-out scheme to the dynamical models near the QCD critical point. Within such framework of static critical fluctuations, the Beam Energy Scan (BES) data of $C_4$ and $κσ^2$ for net protons within different $p_T$ ranges can be roughly described. Besides, the momentum acceptance dependence of higher cumulants at lower collision energies can also be qualitatively described. However, $C_2$ and $C_3$ are always over-predicted due to the positive static critical fluctuations.
