Abstract

In this paper we carry out the boundary form factor program for the A2-affine Toda field theory at the self-dual point. The latter is an integrable model consisting of a pair of particles which are conjugated to each other, that is , and possessing two bound states resulting from the scattering processes 1 + 1 → 2 and 2 + 2 → 1. We obtain solutions up to four-particle form factors for two families of fields which can be identified with spinless and spin-1 fields of the bulk theory. Previously known, as well as new, bulk form factor solutions are obtained as a particular limit of ours. Minimal solutions of the boundary form factor equations for all An-affine Toda field theories are given, which will serve as the starting point for a generalization of our results to higher rank algebras.
