Abstract
We report on our recent calculations of K − and η nuclear quasi-bound states. The underlying \({\bar {K}}N\) and η N 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.
