We report on our recent calculations of K¯ and η nuclear quasi-bound states. The underlying K¯N and ηN scattering amplitudes are constructed within coupled-channel models that capture the physics of the Λ(1405) and N*(1535) resonances, respectively. The role played by the strong energy dependence of the scattering amplitudes near threshold and the importance of self-consistent treatment of the subthreshold energy shift are discussed.

Abstract
We report on our recent calculations of K¯ and η nuclear quasi-bound states. The underlying K¯N and ηN scattering amplitudes are constructed within coupled-channel models that capture the physics of the Λ(1405) and N*(1535) resonances, respectively. The role played by the strong energy dependence of the scattering amplitudes near threshold and the importance of self-consistent treatment of the subthreshold energy shift are discussed.File in questo prodotto:
