We review different exact approaches to string theory. In the context of the Green–Schwarz superstring, we discuss the action in curved backgrounds and its supercoset formulation, with particular attention to superstring backgrounds of the AdS3 type...

Light-cone gauge-fixed sigma models on AdSn×Sn backgrounds play an important role in the integrability formulation of the AdS/CFT correspondence. The string spectrum of the sigma model is gauge independent, however the Hamiltonian and scattering matr... Read More about Inequivalent light-cone gauge-fixings of strings on AdSn×Sn backgrounds.

Elliptic deformations of the AdS 3 × S 3 × T 4 string (2024)
Journal Article
Hoare, B., Retore, A. L., & Seibold, F. K. (2024). Elliptic deformations of the AdS 3 × S 3 × T 4 string. Journal of High Energy Physics, 2024(4), Article 42. https://doi.org/10.1007/jhep04%282024%29042

With the aim of investigating the existence of an integrable elliptic deformation of strings on AdS3 × S3 × T4, we compute the tree-level worldsheet S-matrix of the elliptically-deformed bosonic sigma model on AdS3 × S3 in uniform light-cone gauge. T... Read More about Elliptic deformations of the AdS 3 × S 3 × T 4 string.
