Vector Meson Production and Nucleon Resonance Analysis in the Giessen Coupled-Channel Model
Abstract
We present a nucleon resonance analysis by simultaneously considering all pion- and photon-induced experimental data on the final states γN, πN, 2πN, ηN, KΛ, KΣ, and ωN for energies from the nucleon mass up to √ s = 2 {GeV} . In this analysis we find strong evidence for various higher lying resonances as, e.g., the P13(1900). The ωN production mechanism is dominated by large P11(1710) and P13(1900) contributions.
