Worldsheet scattering in AdS(5) x S**5
TLDR
In this article, the S-matrix in the gauge-fixed sigma model on AdS(5) x S-5 to the leading order in perturbation theory is analyzed.Abstract:
We calculate the S-matrix in the gauge-fixed sigma-model on AdS(5) x S-5 to the leading order in perturbation theory, and analyze how supersymmetry is realized on the scattering states. A mild nonlocality of the supercharges implies that their action on multi-particle states does not follow the Leibniz rule, which is replaced by a nontrivial coproduct. The plane wave symmetry algebra is thus naturally enhanced to a Hopf algebra. This structure mirrors that of the large't Hooft coupling expansion of the S-matrix for the spin chain in the dual super-Yang-Mills theory.read more

Towards integrability for AdS3/CFT2
TL;DR: In this paper, the authors considered supersymmetric string theories on curved backgrounds containing the three-dimensional anti-de-Sitter space, AdS3, and showed how their worldsheet scattering matrix factorises and their spectrum can be efficiently computed by Bethe ansatz techniques.
