Y. Schroder, M. Vepsalainen, A. Vuorinen, Y. Zhu

摘要:

我们确定了高温Yang-Mills理论中剪应力算子的关联函数的次领先阶结果。计算是通过紫外线展开,有效的限制,小距离或大的动量,其结果是用于编写算子乘积展开的欧几里得动量和坐标空间的标量以及闵可夫斯基谱密度。此外,我们的研究结果使我们能够确认和完善最初由Romatschke,儿子和迈耶推导的剪切和规则。

英文摘要:

We determine a next-to-leading order result for the correlator of the shear stress operator in high-temperature Yang-Mills theory. The computation is performed via an ultraviolet expansion, valid in the limit of small distances or large momenta, and the result is used for writing operator product expansions for the Euclidean momentum and coordinate space correlators as well as for the Minkowskian spectral density. In addition, our results enable us to confirm and refine a shear sum rule originally derived by Romatschke, Son and Meyer.
