Dressing Factors and Mirror Thermodynamic Bethe Ansatz for mixed-flux AdS3/CFT2

We complete the derivation of the dressing factors for the $Ad{S}_3\times S^3\times T^4$ S matrix with mixed Ramond–Ramond and Neveu-Schwarz-Neveu-Schwarz flux, in the “string” and “mirror” kinematics. Using these, we propose the mirror Thermodynamic Bethe Ansatz equations which describe the spectrum of the model at any string tension.
