摘要：

We study pion- and photo-induced reactions on the nucleon within a coupled-channel effective Lagrangian model to extract baryon resonance properties. All ;available experimental data on the (gamma/pi)N -> pi N, 2 pi N, eta N, omega N reactions in the energy region m(pi) + m(N) <= root s <= 2GeV are simultaneously analysed to constrain baryon resonance parameters. A good description agreement of calculated observables with experiment is achieved and baryon resonance parameters are extracted.
