Correlators of Wilson loops and local operators from multi-matrix models and strings in AdS

Understand

We study correlation functions of Wilson loops and local operators in a subsector 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.
