标题： Finite temperature QCD: progress and outstanding problems

摘要： 我回顾了有限温度量子色动力学数值模拟的最新进展，并讨论了一些尚未解决的问题的状态。 其中包括：（1）关于确定全QCD中“相变”温度的近期结果的讨论，（2）对Polyakov环变量的标度分析，从而确定组成夸克的自由能， （3）研究双味QCD中相变附近的临界行为， （4）关于Wilson费米子热力学模拟中的问题和新结果的讨论，（5）具有混合基本/伴随作用的纯规范理论的近期结果，以及（6）包含动力学费米子的态方程的非微扰确定。 最后，我简要提及了在构建脱拘禁和手征对称性恢复现象学方面的新发展，即（7）对偶超导模型和（8）瞬子模型。 显示英文摘要

摘要： I review recent progress in numerical simulations of finite temperature quantum chromodynamics and discuss the status of some outstanding problems. Included is (1) a discussion of recent results determining the temperature of the ``phase transition'' in full QCD, (2) a scaling analysis of the Polyakov loop variable, leading to the determination of a constituent quark free energy, (3) studies of critical behavior near the phase transition in two-flavor QCD, (4) a discussion of problems and new results in thermodynamic simulations with Wilson fermions, (5) recent results in pure gauge theory with a mixed fundamental/adjoint action, and (6) the nonperturbative determination of the equation of state with dynamical fermions included. Finally I mention briefly new developments in efforts to construct a phenomenology of deconfinement and chiral symmetry restoration, namely (7) the dual superconducting model and (8) the instanton model.
