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 × H g−h /H k+g−h. The perturbed models are closely related tô 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. Over the past few years many new integrable quantum field theories in two dimensions have been constructed as… CONTINUE READING
