摘要
We propose an alternative method to study the saddle point equation in the strong coupling limit for the Wilson loop in N = 2 D = 4 super-Yang-Mills with an SU(N) gauge group and 2N hypermultiplets. This method is based on an approximation of the integral equation kernel which allows us to solve the simplified problem exactly. To determine the accuracy of this approximation, we compare our results with those obtained recently by Passerini and Zarembo. Although less precise, this simpler approach provides an explicit expression for the density of eigenvalues that is used to derive the planar free energy.
