Abstract
A combined analysis of photoproduction data on gamma p -> pi N, eta N was performed including the data on K Lambda and K Sigma. The data are interpreted in an isobar model with s-channel baryon resonances and pi, p(omega), K, and K * exchange in the t-channel. Three baryon resonances have a substantial coupling to eta N, the well-known N(1535)S-11, N(1720)P-13, and N(2070)D-15. The inclusion of data with open strangeness reveals evidence for further new resonances, N(1840)P-11, N(1875)D-13 and, with weaker evidence, for N(2170)D-13.
