K- nuclear potentials from in-medium chirally motivated models
Original language description
A self-consistent scheme for constructing K-nuclear optical potentials from subthreshold in-medium (K) over bar N s-wave scattering amplitudes is presented and applied to analysis of kaonic atoms data and to calculations of K(-) quasibound nuclear states. The amplitudes are taken from a chirally motivated meson-baryon coupled-channel model, both at the Tomozawa-Weinberg leading order and at the next to leading order. Typical kaonic atoms potentials are characterized by a real part -Re V(K-)(chiral) = 855 MeV at nuclear matter density, in contrast to half this depth obtained in some derivations based on in-medium (K) over bar N threshold amplitudes.
