Calculations of kaonic nuclei based on chiral meson-baryon coupled channel interaction models

Abstract

We present our latest calculations of K−-nuclear quasi-bound states using a self-consistent scheme for constructing K−-nuclear potentials from various subthreshold chirally inspired K̄N scattering amplitudes. We consider in-medium versions of the scattering amplitudes taking into account Pauli blocking in the intermediate states. The resulting K− binding energies as well as the widths exhibit the same A dependence, however, the binding energies strongly depend on the model used.
