noindent “Integrability meeting ENS/IPhT'' I will describe how the integrability-based hexagonalization approach can be used to compute non-planar corrections to correlation functions in AdS/CFT at finite coupling. The computation is based on a tessellation of the worldsheet into integrable hexagon patches, and it naturally includes a discretization of the string theory moduli space.
