Channels included in the model are γN, πN, ηN, KΛ, KΣ, ππN ( π∆, πρ, πσ). About 30,000 data points are included in the fits with about 350 model parameters which define phenomenologically the mesonexchange interactions between the considered mesonbaryon channels and the quarkgluon excitations of the nucleon to about 20 excited states. The resulting partialwave amplitudes can be used to:
(1) Extract nucleon resonance parameters,
(2) investigate meson production reactions on nuclei in the nucleon resonance region,
(3) predict the medium effects on the propagation of mesons and nucleon resonances in hadron matter.
