Ladders for Wilson Loops Beyond Leading Order
arXiv:1206.7117 · doi:10.1007/JHEP09(2012)057
Abstract
We set up a general scheme to resum ladder diagrams for the quark-anti-quark potential in N=4 super-Yang-Mills theory, and do explicit calculations at the next-to-leading order. The results perfectly agree with string theory in AdS(5)xS(5) when continued to strong coupling, in spite of a potential order-of-limits problem.
