QUANTUM AFFINE SYMMETRY AND SCATTERING AMPLITUDES OF THE IMAGINARY COUPLED D(4)((3)) AFFINE TODA FIELD THEORY

摘要

An exact S-matrix is conjectured for the imaginary coupled d(4)((3)) affine Toda field theory, using the U-q(g(2)((1))) symmetry. It is shown that this S-matrix is consistent with the results for the case of real coupling using the breather-particle correspondence. For q a root of unity it is argued that the theory can be restricted to yield Phi(11/14) perturbations of WA(2) minimal models and the restriction is performed for the (3,p') minimal models.
