Bonn-Gatchina partial wave analysis of pion - nucleon and photo - nucleon reactions: nucleon states in the mass region around 2 Gev

 

The status of the Bonn-Gatchina partial wave analysis of the pion-nucleon and photon-nucleon collision reactions is presented. We found an evidence for existence of unknown resonances in the mass region around 2 GeV. We also report the analysis of the high statistic MAMI data on the eta-photoproduction where a narrow structure in the region of 1.7 GeV is observed
