Abstract

We propose dressing factors for massive excitations of the worldsheet S matrix of $A d S_{3} \times S^{3} \times S^{3} \times S^{1}$ supported by mixed Ramond--Ramond and Neveu-Schwarz--Neveu-Schwarz flux, in the "string" and "mirror" kinematics. Our proposal is compatible with crossing and unitarity, and it reproduces the available perturbative results for any ratio of the two three-spheres' radii.
