摘要：

Previous results on form factors for the scaling Ising and the sinh-Gordon models are extended to general Z(N)-Ising and affine A(N-1)-Toda quantum field theories. In particular result for order, disorder parameters and para-Fermi field sigma(Q)(x), mu((Q) over bar)(x) and psi(Q)(x) are presented for the Z(N)-model. For the A(N-1)-Toda model form factors for exponentials of the Toda fields are proposed. The quantum field equation of motion is proved and the mass and wave function renormalization. are calculated exactly. (C) 2003 Elsevier B.V. All rights reserved.
