一种强耦合下副导红外极的通用结构

Universal structure of subleading infrared poles at strong coupling

Luis F. Alday

摘要:

最近,维数正则化规范理论的次主导红外奇异性被提出了一个简明的表达式。对于共形理论,这种关系涉及到一个普适程函贡献加上一个非程函贡献,与大自旋扭转二算子的反常维数中的次引导项有关。本文利用AdS/CFT对应,对N=4 SYM的强耦合情形,检验了这一猜想.

英文摘要:

Recently a concise expression for the subleading infrared singularity of dimensional-regularized gauge theories has been proposed. For conformal theories, such relation involves a universal eikonal contribution plus a non-eikonal contribution, related to the subleading term in the anomalous dimension of twist two operators with large spin. In this note we make use of the AdS/CFT correspondence in order to check such conjecture at strong coupling for the case of N=4 SYM.
