Unified theory of N-N and π-d scattering

Using a time ordered diagrammatic method, we derive a set of linear integral equations that couple the N-N to the π-d channel and satisfy two- and three-body unitarity. The resultant equations have dressed propagators for the nucleons, and dressed form factors for the πNN vertex. The inclusion of the full π-N amplitude in the P₁₁ channel leads to a dressing of both the πNN vertex and N-N propagator without changing the basic structure of the equations.
