Chirally motivated separable potential model for eta N amplitudes

Result description

We analyze the eta N interaction using a coupled channel separable potential model that implements the chiral symmetry. The model predicts an eta N scattering length Ha(eta N) approximate to 0.7 fm and in-medium subthreshold attraction most likely sufficient to generate eta-nuclear bound states. The energy dependence of the eta N 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.
