The impact of ${\mathbf{K}}^{+}\mathbf{\Lambda }$ photoproduction on the resonance spectrum

D. Rönchen, M. Döring, U. -G. Meißner

The Jülich-Bonn coupled-channel framework is extended to $K^{+}\Lambda$ photoproduction. The spectrum of nucleon and $\Delta$ resonances is extracted from simultaneous fits to several pion-indu…
