Title: 强耦合各向异性等离子体中的喷注淬火

Abstract: The jet quenching parameter of an anisotropic plasma depends on the relative orientation between the anisotropic direction, the direction of motion of the parton, and the direction along which the momentum broadening is measured. We calculate the jet quenching parameter of an anisotropic, strongly coupled N=4 plasma by means of its gravity dual. We present the results for arbitrary orientations and arbitrary values of the anisotropy. The anisotropic value can be larger or smaller than the isotropic one, and this depends on whether the comparison is made at equal temperatures or at equal entropy densities. We compare our results to analogous calculations for the real-world quark-gluon plasma and find agreement in some cases and disagreement in others. Show Chinese abstract

Abstract: 具有各向异性特性的等离子体的喷射淬灭参数依赖于各向异性方向、部分子运动方向以及动量展宽测量方向之间的相对取向。 我们利用其引力对偶计算了具有各向异性和强耦合的N=4等离子体的喷射淬灭参数。 我们给出了任意取向和各向异性任意值的结果。 各向异性值可能大于或小于各向同性值，这取决于比较是在相等温度还是相等熵密度下进行。 我们将结果与现实世界中的夸克-胶子等离子体的类似计算进行了比较，发现有些情况下一致，有些情况下不一致。
