Abstract

A combined analysis of photoproduction data on γp to πN, 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, rho,(omega), K, and K^* exchange in the t--channel. Three baryon resonances have a substantial coupling to eta N, the well known N(1535)S₁₁, N(1720)P₁₃, and N(2070)D₁₅. The inclusion of data with open strangeness reveals the presence of further new resonances, N(1840)P₁₁, N(1875)D₁₃ and N(2170)D₁₃.
