Cusp anomalous dimension in maximally supersymmetric Yang-Mills theory at strong coupling

arXiv:0708.3933 · doi:10.1103/PhysRevLett.100.091601

Abstract

We construct an exact analytical solution to the integral equation which is believed to describe logarithmic growth of the anomalous dimensions of high spin operators in planar N=4 super Yang-Mills theory and use it to determine the strong coupling expansion of the cusp anomalous dimension.
