有限密度下格点量子色动力学的研究进展

Recent progress in lattice QCD at finite density

Shinji Ejiri

摘要:

本文综述了有限密度下格点量子色动力学的最新进展。讨论了有限温度和有限密度下的QCD相图和状态方程。特别是,我们专注于在高密度区终止一阶相变线的临界点。临界点是在重离子碰撞实验中可能发现的最有趣的特征之一。我们总结了目前关于QCD相图中临界点存在性的讨论,并讨论了通过数值模拟寻找临界点的一些尝试。

英文摘要:

We review recent progress in lattice QCD at finite density. The phase diagram of QCD and the equation of state at finite temperature and density are discussed. In particular, we focus on the critical point terminating a first order phase transition line in the high density region. The critical point is one of the most interesting features that may be discovered in heavy-ion collision experiments. We summarize the current discussion on the existence of a critical point in the QCD phase diagram and discuss some attempts to find the critical point by numerical simulations.
