论文摘要
我们报告了正在进行的努力解决QCD热力学中一个重要的开放问题的努力，即评估在弱耦合扩展中订购$ g^6 $的压力，对应于四个循环。特别是，我们确定了具有较低环因素的一类贡献的Feynman Sum-Integrals，描述了张量分解的形式主义，并设法将它们映射到文献中已经评估过的标量主汇总积分中。
We report on ongoing efforts to tackle an important open problem in QCD thermodynamics, namely an evaluation of the pressure to order $g^6$ in a weak-coupling expansion, corresponding to four loops. In particular, we identify a class of contributing Feynman sum-integrals with lower-loop factors, describe the formalism to tensor decompose those, and manage to map them onto scalar master sum-integrals that have already been evaluated in the literature.
