Description
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 the resonances P31(1750), P13(1900), P33(1920), and D13(1950). The ωN production mechanism is dominated by large P11(1710) and P13(1900) contributions. In this second part we present the results on the photoproduction reactions and the electromagnetic properties of the resonances. The inclusion of all important final states up to √(s)=2 GeV allows for estimates on the importance of the individual states for the GDH sum rule
