Hexagonalization in $Ad{S}_3\times S^3\times T^4$: Mirror Corrections

Abstract

A big open problem in $Ad{S}_3\times S^3\times T^4$ holographic duality is to compute the CFT data of the dual theory. In this direction recently it was introduced the hexagonalization framework in the $Ad{S}_3$ context. It allows the computation of the structure constants of the CFT${}_2$ dual in the planar limit non-perturbatively, however in this proposal it was introduced only the asymptotic part of the hexagon valid for correlators with asymptotically large bridge lengths. In this work we complete this picture by computing the so called mirror corrections that allow to describe structure constants for finite bridge lengths and as a byproduct we also prove that the half-BPS operators in the theory do not receive these corrections. We end up by giving the first steps on using hexagonalization to compute $n$-point functions in the $Ad{S}_3\times S^3\times T^4$ holographic duality.
