%X The Jülich-Bonn coupled-channel framework is extended to K+Λ photoproduction. The spectrum of nucleon and Δ resonances is extracted from simultaneous fits to several pion-induced reactions in addition to pion, eta and K+Λ photoproduction off the proton. More than 40000 data points up to a center-of-mass energy of E∼2.3 GeV including recently measured double-polarization observables are analyzed. The influence of the γp→K+Λ channel on the extracted resonance parameters and the appearance of states not seen in other channels is investigated. The Jülich-Bonn model includes effective three-body channels and guarantees unitarity and analyticity, which is a prerequisite for a reliable determination of the resonance spectrum in terms of poles and residues.
