Abstract
In this paper we carry out the boundary form factor program for the A2affine Toda field theory at the selfdual 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 fourparticle form factors for two families of fields which can be identified with spinless and spin1 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 Anaffine Toda field theories are given, which will serve as the starting point for a generalization of our results to higher rank algebras.
