| Title | Light baryon resonances from a coupled-channel study including KSigma photoproduction | ||||
| Abstract | The Julich-Bonn dynamical coupled-channel approach is extended to include KSigma photoproduction off the proton. Differential cross section and (double) polarization data for K^+ Sigma^0 and K^0 Sigma^+ are analysed simultaneously with the pion- and photon-induced production of pi N, eta N, K Lambda, and K Sigma final states, totaling more than 67,000 data points for center-of-mass energies W < 2.4 GeV. Based on the fit results the spectrum of N? and Delta resonances is extracted in terms of pole positions and residues. We discuss the impact of the gamma p -> K Sigma channels in detail and investigate the influence of recent polarization data for eta p photoproduction. | ||||
