Tree-level S matrix for -deformed AdS3 strings

Marco Costantino, Silvia Penati, Alessandro Sfondrini

We consider the supersymmetric -deformation of superstrings and compute its perturbative bosonic tree-level worldsheet S matr…

On the dressing factors

Sergey Frolov, Alessandro Sfondrini

We propose dressing factors for massive excitations of the worldsheet S matrix of supported by mixed Ramond--Ramond and Neveu-Schwarz--Neveu-S…

Relativistic limit on the string worldsheet

Emanuele Maria Cattaneo, Davide Polvara, Alessandro Sfondrini

We study the relativistic limit of the worldsheet S matrix of strings in the presence of mixed Ramond-Ramond (RR) and Neveu-Schwarz-Neveu-S…

Revisiting the tensionless limit of pure-Ramond-Ramond AdS3/CFT2

Alberto Brollo, Dennis le Plat, Alessandro Sfondrini

We revisit the numerical solution of the mirror TBA equations for pure--Ramond-Ramond strings on in the tensionless limit. Our analysis uses the recentl…

AdS3 Integrability, Tensionless Limits, and Deformations: A Review

Fiona K. Seibold, Alessandro Sfondrini

Motivated by the recent advances in the understanding of integrability for backgrounds, we present a lightning review of this approach, with particular attention to the "te…

Thermodynamics of integrable N=2 theories, squared

Xavier Kervyn, Davide Polvara, Alessandro Sfondrini

In arXiv:2306.17553 a new supersymmetric integrable QFT was constructed from the relativistic limit of the worlsdheet theory of AdS ST superstrings with m…
