Integrable bootstrap for AdS3/CFT2 correlation functions

We propose an integrable bootstrap framework for the computation of correlation functions superstrings in $AdS_3\times S^3\times T^4$ backgrounds supported by arbitrary mixture or Ramond-Ramond and Neveu-Schwarz-Neveu-Schwarz fluxes. The extends "hexagon tessellation" approach which was originally proposed $AdS_5\times S^5$ first time it demonstrates its applicability to other (less supersymmetric) setups. work out hexagon form factor two-particle states, including dressing factors follow from those spectral problem, we show that satisfies non-trivial consistency conditions. a principle, slightly different S^5$, allows extend arbitrarily many particles. Finally, compare predictions with some protected operators. Possible applications this construction include study wrapping corrections, higher-point functions, non-planar corrections.
