Near-threshold K(-)d scattering and propertiies of kaonic deuterium
Result description
We calculated the ls level shifts and widths of kaonic deuterium, corresponding to accurate results on near-threshold antikaon-deuteron scattering. The Lippmann-Schwinger eigenvalue equation with a strong K--d and Coulumb potentials was solved. The two-body K--d potentials reproduce the near-theshold elastic amplitudes of K(-)d scattering obtained from the three-body Alt-Grassberger-Sanddhas equations with the coupled channels using two versions of the (k)over barN-pi Sigma potentials. The new (K) overbarN-pi Sigma potentials reproduce the very recent SIDDHARTA data on kaonic hydrogen, experimental data on K- p scattering and have one- or two-pole versions of the Lambda(1405) resonance.
