本文给出了有限温度下Landau规范Yang-Mills理论中的非微扰关联函数。结果是从功能重整化组内的自洽近似方案。特别地，我们计算了胶子传播子的磁分量和电分量，以及三个和四个胶子顶点。在有限温度下，我们还给出了鬼传播子和鬼胶子顶点。我们的结果的传播面临的晶格模拟和我们的德拜质量相比，硬热环微扰理论。
We present non-perturbative correlation functions in Landau-gauge Yang-Mills theory at finite temperature. The results are obtained from the functional renormalisation group within a self-consistent approximation scheme. In particular, we compute the magnetic and electric components of the gluon propagator, and the three- and four-gluon vertices. We also show the ghost propagator and the ghost-gluon vertex at finite temperature. Our results for the propagators are confronted with lattice simulations and our Debye mass is compared to hard thermal loop perturbation theory.
