On the $A d S_{3} \times S^{3} \times S^{3} \times S^{1}$ dressing factors

Sergey Frolov, Alessandro Sfondrini

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-S…

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

Sergey Frolov, Davide Polvara, Alessandro Sfondrini

We complete the derivation of the dressing factors for the $A d S_{3} \times S^{3} \times T^{4}$ S matrix with mixed Ramond--Ramond and Neveu-Schwarz-Neveu-Schwarz flux, in the "string" and…

Exchange relations and crossing

Sergey Frolov, Davide Polvara, Alessandro Sfondrini

We discuss the scattering matrix of two-dimensional integrable QFTs whose fields obey non-trivial exchange relations. We show that crossing equations for such models have to be mod…

Massive dressing factors for mixed-flux AdS $_{3}$ /CFT $_{2}$

Sergey Frolov, Davide Polvara, Alessandro Sfondrini

We follow up on our proposal for dressing factors for the mixed-flux $A d S_{3} \times S^{3} \times T^{4}$ background presented in arXiv:2402.11732. We discuss in detail the analytic propert…

Dressing Factors for Mixed-Flux $A d S_{3} \times S^{3} \times T^{4}$ Superstrings

Sergey Frolov, Davide Polvara, Alessandro Sfondrini

We propose the dressing factors for the scattering of massive particles on the worldsheet of mixed-flux $A d S_{3} \times S^{3} \times T^{4}$ superstrings, in the string and mirror kinematic…

Comments on Integrability in the Symmetric Orbifold

Sergey Frolov, Alessandro Sfondrini

We present a map between the excitation of the symmetric-product orbifold CFT of $T^{4}$ , and of the worldsheet-integrability description of $A d S_{3} \times S^{3} \times T^{4}$ of Lloyd, Ohl…
