S-matrices for Perturbed N=2 Superconformal Field Theory from quantum groups

Abstract

S-matrices for integrable perturbations of $N=2$ superconformal field theories are studied. The models we consider correspond to perturbations of the coset theory $G_k\times H_{g-h}/H_{k+g-h}$. The perturbed models are closely related to $\hat{G}$-affine Toda theories with a background charge tuned to $H$. Using the quantum group restriction of the affine Toda theories we derive the S-matrix.
