Tree-level S matrix for $\lambda$-deformed AdS3 strings

Marco Costantino, Silvia Penati, Alessandro Sfondrini

We consider the supersymmetric $\lambda$-deformation of ${\text{AdS}}_3\times {\text{S}}^3\times {\text{T}}^4$ superstrings and compute its perturbative bosonic tree-level worldsheet S matri…
