Calculations of K- nuclear quasi-bound states based on chiral meson-baryon amplitudes
Original language description
In-medium (K) over bar N scattering amplitudes developed within a new chirally motivated coupled-channel model due to Cieply and Smejkal that fits the recent SIDDHARTA kaonic hydrogen Is level shift and width are used to construct K- nuclear potentials for calculations of K- nuclear quasi-bound states. The strong energy and density dependence of scattering amplitudes at and near threshold leads to K- potential depths -Re V-K approximate to 80-120 MeV. Self-consistent calculations of all K- nuclear quasi-bound states, including excited states, are reported. Model dependence, polarization effects, the role of p-wave interactions, and two-nucleon K- NN -> YN absorption modes are discussed. The K- absorption widths Gamma(K) are comparable or even larger than the corresponding binding energies B-K for all K- nuclear quasi-bound states. exceeding considerably the level spacing. This discourages search for K- nuclear quasi-bound states in any but the lightest nuclear systems.
