Abstract

We present a nucleon resonance analysis by simultaneously considering all pion- and photon-induced experimental data on the final states γN\gamma N, πN\pi N, 2πN2\pi N, ηN\eta N, KΛK\Lambda, KΣK\Sigma, and ωN\omega N for energies from the nucleon mass up to s=2\sqrt s = 2 GeV. In this analysis we find strong evidence for various higher lying resonances as, e.g., the P13(1900)P_{13}(1900). The ωN\omega N production mechanism is dominated by large P11(1710)P_{11}(1710) and P13(1900)P_{13}(1900) contributions.
