Lattice QCD Thermodynamics with Physical Quark Masses

R. A. Soltz, C. DeTar, F. Karsch, Swagato Mukherjee, P. Vranas

摘要:

在过去的几年中,新的物理方法和算法以及最新的超级计算机已经能够使用格点规范理论的数值模拟与前所未有的控制系统误差的QCD热力学相变的研究。这在很大程度上是用物理夸克质量进行连续外推的能力的结果。本文综述了格点量子色动力学热力学的最新进展,主要集中在利用物理夸克质量所得到的结果:交叉温度、状态方程和夸克数涨落。此外,我们特别强调的计算是直接相关的相对论性重离子碰撞在RHIC和LHC的研究。

英文摘要:

Over the past few years new physics methods and algorithms as well as the latest supercomputers have enabled the study of the QCD thermodynamic phase transition using lattice gauge theory numerical simulations with unprecedented control over systematic errors. This is largely a consequence of the ability to perform continuum extrapolations with physical quark masses. Here we review recent progress in lattice QCD thermodynamics, focussing mainly on results that benefit from the use of physical quark masses: the crossover temperature, the equation of state, and fluctuations of the quark number susceptibilities. In addition, we place a special emphasis on calculations that are directly relevant to the study of relativistic heavy ion collisions at RHIC and the LHC.
