Scattering in soliton models and boson-exchange descriptions

We analyze the relationship between the conventional one-boson-exchange model (OBE) for nuclear forces with the description of the nucleon as a soliton within the context of the two-dimensional sine-Gordon model. We find that the soliton-soliton S matrix contains poles and residues compatible with the ones used in the OBE. Implications of this result for the four-dimensional case are briefly discussed.
