有限温度场论中热态QGP的液相行为

Liquid behavior of hot QGP in the finite temperature field theory

Hui Liu, Defu Hou, Jiarong Li

摘要:

本文比较了硬热回线和完全单回线的色散关系。结果表明,在动态屏蔽制度,完全的单回路计算提出了一个突出的阈值频率,低于该频率没有纯虚模生存。这种现象是负责振荡的静态介质中的潜力,并最终导致在阻尼振荡的径向分布函数。我们认为这种典型的形状就是液态QGP的足迹。

英文摘要:

In this paper, we compare the dispersion relations of hard thermal loop and complete one loop. It is shown that in the dynamical screening regime, the completely one-loop calculation presents a prominent threshold frequency, below which no pure imaginary mode survives. This phenomenon is responsible for the oscillatory static in-medium potential and ultimately results in a damping oscillation of the radial distribution function. We consider this typical shape is the footprint of liquid QGP.
