论文摘要

通过强耦合的解构等等离子体移动的重夸克具有全息偶的描述,作为在黑色brane几何形状中移动的弦。我们将全息化的Wilsonian重新归一化方法应用于重型夸克的全息有效弦乐双重动作。有效的作用仅取决于黑毛层地平线和径向置于径向方向的截止物之间的几何形状,与双重理论的IR相对应。我们在有效作用中得出了系数的RG流程方程,并表明作用在重夸克上的力与截止位置无关。有关紫外线的所有信息都隐藏在RG流程方程的集成常数中。这种类型的方法可用于改善半全显示模型,其中扰动QCD和IR通过全息模型描述了紫外线。

A heavy quark moving through a strongly coupled deconfined plasma has a holographic dual description as a string moving in a black brane geometry. We apply the holographic Wilsonian renormalization method to derive a holographic effective string action dual to the heavy quark. The effective action only depends on the geometry between the black brane horizon and a cutoff localized in the radial direction, corresponding to the IR of the dual theory. We derive RG flow equations for the coefficients in the effective action and show that the force acting on the heavy quark is independent of the position of the cutoff. All the information about the UV is hidden in integration constants of the RG flow equations. This type of approach could be used to improve semi-holographic models where the UV is described by perturbative QCD and the IR by a holographic model.
