Abstract

New integral representations for form factors in the two parametric SS model are proposed. Some form factors in the parafermionic sine-Gordon model and in an integrable perturbation of SU(2) coset conformal field theories are straightforwardly obtained by different quantum group restrictions. Numerical checks on the value of the central charge are performed.
