Chirally motivated separable potential model for ηN amplitudes

We analyze the ηN interaction using a coupled channel separable potential model that implements the chiral symmetry. The model predicts an ηN scattering length ℜaηN≈0.7 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 N⋆(1535) and N⋆(1650) is presented.
