In-medium eta N interactions and eta nuclear bound states
Original language description
The in-medium eta N interaction near and below threshold is constructed from a free-space chirally-inspired meson-baryon coupled-channel model that captures the physics of the N* (1535) baryon resonance. Nucleon Pauli blocking and hadron self-energies are accounted for. The resulting energy-dependent in-medium interaction is used in self-consistent dynamical calculations of eta nuclear bound states. Narrow states of width Gamma eta less than or similar to 2 MeV are found across the periodic table, beginning with A >= 10, for this in-medium coupled-channel interaction model. The binding energy of the 1477 state increases with A, reaching a value of B-1s (eta) approximate to 15 MeV. The implications of our self-consistency procedure are discussed with respect to procedures used in other works.
