摘要：

在这篇综述文章中，我们讨论了微扰理论的现状和未来的前景，作为一种手段，研究平衡热力学和近平衡输运性质的退禁闭QCD物质。我们首先简要介绍了一般的主题，之后，我们回顾了一些详细的基础和现代技术的实时和非实时形式主义的热场论，包括例如在实时形式主义和所需的处理软和共线贡献的示意图中使用的不同的基础。在此之后，我们讨论了这些技术的应用现状，包括电磁率，输运系数，喷注猝灭，重夸克和夸克偶素，以及热夸克-胶子等离子体和冷密夸克物质的状态方程。最后，我们的结论与我们的看法，该领域的未来方向，即我们如何预期微扰计算，以促进我们的集体理解强相互作用的物质在未来几年。

英文摘要：

In this review article, we discuss the current status and future prospects of perturbation theory as a means of studying the equilibrium thermodynamic and near-equilibrium transport properties of deconfined QCD matter. We begin with a brief introduction to the general topic, after which we review in some detail the foundations and modern techniques of the real- and imaginary-time formalisms of thermal field theory, covering e.g. the different bases used in the real-time formalism and the resummations required to deal with soft and collinear contributions. After this, we discuss the current status of applications of these techniques, including topics such as electromagnetic rates, transport coefficients, jet quenching, heavy quarks and quarkonia, and the Equations of State of hot quark-gluon plasma as well as cold and dense quark matter. Finally, we conclude with our view of the future directions of the field, i.e. how we anticipate perturbative calculations to contribute to our collective understanding of strongly interacting matter in the coming years.
