Abstract: (Springer)
We consider various integrable two-parameter deformations of the AdS3_{3} × S3^{3} × T4^{4} superstring with quantum group symmetry. Working on the string worldsheet in light-cone gauge and to quadratic order in fermions, we obtain their common massive tree-level two-body S matrix, which matches the expansion of the conjectured exact q-deformed S matrix. We then analyze the behavior of the exact S matrix under mirror transformation — a double Wick rotation on the worldsheet — and find that it satisfies a mirror duality relation analogous to the distinguished q-deformed AdS5_{5} × S5^{5} S matrix in the one parameter deformation limit. Finally, we show that the fermionic q-deformed AdS5_{5} × S5^{5} S matrix also satisfies such a relation.
