Eta-mesic nuclei

Original language description

In this contribution we report on theoretical studies of eta nuclear quasi-bound states in few- and many-body systems performed recently by the Jerusalem-Prague Collaboration . Underlying energy-dependent eta N interactions are derived from coupled-channel models that incorporate the N*(1535) resonance. The role of self-consistent treatment of the strong energy dependence of subthreshold eta N amplitudes is discussed. Quite large downward energy shift together with rapid decrease of the eta N amplitudes below threshold result in relatively small binding energies and widths of the calculated eta nuclear bound states. We argue that the subthreshold behavior of eta N scattering amplitudes is crucial to conclude whether eta nuclear states exist, in which nuclei the eta meson could be bound and if the corresponding widths are small enough to allow detection of these eta nuclear states in experiment.
