New narrow nucleon N*(1685)Vyacheslav Kuznetsov1 and •Maxim Polyakov21Kyungpook National University, 702-701, Daegu, Republic of Korea — 2Institut für Theoretische Physik II, Ruhr-Universität Bochum, 44780 Bochum

We argue that the existence of a new narrow (Gamma <25 MeV) nucleon resonance N*(1685) is strongly supported by recent data on eta-photoproduction off the nucleon. The resonance has much stronger photo-coupling to the neutron than to the proton. This nucleon resonance is a good candidate for the non-strange member of the exotic anti-decouplet of baryons -- the partner of the pentaquark Theta+. All up to date known properties of new N*(1685) are summarized.
