Ladder Limit for Correlators of Wilson Loops

Understand

We study the correlator of concentric circular Wilson loops for arbitrary radii, spatial and internal space separations.

• For real values of the parameters specifying the dual string configuration, a typical Gross-Ooguri phase transition is observed.
• In addition, we explore some analytic continuation of a parameter $\gamma$ that characterizes the internal space separation.
• This enables a ladder limit in which ladder resummation and string theory computations precisely agree in the strong coupling limit.
