A model for calculating the pion-nucleon amplitude in the region of the higher resonances is presented. Using partial wave dispersion relations, it attempts to take into account the inelastic process N + T 4 N + a + a by assuming that the final particles interact strongly in pairs, and treating the
A self-consistent analysis of pion scattering and pion photoproduction within a coupled channels dynamical model is presented. In the case of pion photoproduction, we obtain background contributions to the imaginary part of the S-wave multipole which differ considerably from the result based on the
