Abstract
We analyze the ηN interaction using a coupled channel separable potential model that implements the chiral symmetry. The model predicts an ηN scattering length âaηNâ0.7 fm and in-medium subthreshold attraction most likely sufficient to generate η-nuclear bound states. The energy dependence of the ηN amplitude and pole content of the model are discussed. An idea of the same origin of the baryon resonances Nâ(1535) and Nâ(1650) is presented.
