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

Original language description

We report on our recent self-consistent calculations of anti K-nuclear quasi-bound states using a anti K single-nucleon optical potential derived from 6 different chiral meson-baryon coupled-channel interaction models. They yield quite diverse anti K 1s binding energies and rather small anti K decay widths. Next, we supplement the anti K single-nucleon potential by a phenomenological anti K multinucleon potential introduced recently to achieve good fits to kaonic atom data [1]. We demonstrate a decisive impact of the anti K multinucleon interactions on the widths of anti K-nuclear states. The resulting widths are considerably larger than the corresponding binding energies. The only two models accepted by the analysis of Ref. [1] even do not yield any kaonic nuclear bound state in many-body nuclear systems with mass number A leq 40.
