Hypernuclear potentials and the pseudoscalar meson exchange contribution

Abstract

The pieces of the hypernuclear strangeness violating potential due to the pseudoscalar meson exchanges are derived using methods which were successfully applied to hyperon nonleptonic decays. The estimates are tested by comparison with measured hyperon nonleptonic decay amplitudes. All isospin changes $ΔI=1/2$ and $ΔI=3/2$ are included in the derived potential. All calculational methods used are reviewed and described in detail.
