摘要
We study correlation functions of Wilson loops and local operators in a sector of N = 4 SYM which preserves two supercharges. Localization arguments allow to map the problem to a calculation in bosonic two-dimensional Yang-Mills theory. In turn, this can be reduced to computing correlators in certain Gaussian multi-matrix models. We focus on the correlation function of a Wilson loop and two local operators, and solve the corresponding three-matrix model exactly in the planar limit. We compare the strong coupling behavior to string theory in AdS(5) x S-5, finding precise agreement. We pay particular attention to the case in which the local operators have large R-charge J at strong coupling behavior to string theory in Ads(5) X S-5,S- finding precise agreement. We pay particular attention to the case in which the local operators have large R-charge J similar to root lambda at strong coupling.
