Giessen coupled-channel model pion and photon induced reactions — •Vitaly Shklyar, Horst Lenske, and Ulrich Mosel — Institut für Theoretische Physik, Universität Giessen

Pion- and photon-induced reactions are investigated within a unitary coupled-channel effective Lagrangian model in the resonance energy region. The π N, ρ N, πΔ, σ N, η N, ω N, KΛ, KΣ final states are treated on the same basis. Two-pion channels are described by an explicit treatment of meson dynamics. The coupling constants are constrained by comparison with the available experimental data. Recent results are presented and discussed.
