- Abstract
We investigated different properties of the K d system. First, the near-threshold elastic amplitudes of K d scattering were calculated from the three-body Alt-Grassberger-Sandhas equations with the coupled channels using four versions of the -KN-πΣ potentials. The potentials reproduce the very recent SIDDHARTA or older KEK experimental data on kaonic hydrogen, data on K p scattering and have one- or two-pole structure of the Λ(1405) resonance. Second, the 1 s-level shifts and widths of kaonic deuterium, corresponding to the results on near-threshold antikaon-deuteron scattering, were calculated. The question of existence of a strong quasi-bound state in the K d system was also investigated.
