Title Handling Handles: Nonplanar Integrability
Abstract We propose an integrability setup to compute correlators of gauge invariant operators at any value of the ’t Hooft coupling at any order in the large N ’t Hooft expansion in N = 4 SYM. It is a three step proposal where one first polygonalizes any string worldsheet in all possible ways, next we triangulate all polygons in these tesselations and finally we sprinkle mirror particles at any triangle junction to obtain the full correlator. In this talk, I will put our proposal to test against a non-planar 4pt correlator of large 1/2–BPS operators at one and two loops.
