Photon- and meson-induced reactions on the nucleon

Abstract

In an unitary effective Lagrangian model we develop a unified description of both meson scattering and photon-induced reactions on the nucleon. Adding the photon to an already existing model for meson-nucleon scattering yields both Compton and meson photoproduction amplitudes. In a simultaneous fit to all available data involving the final states $\gamma N$, $\pi N$, $\pi \pi N$, $\eta N$ and $K\Lambda$ the parameters of the nucleon resonances are extracted.
