COUPLED-CHANNELS FADDEEV CALCULATION OF THE K-d SCATTERING LENGTH

We investigated the dependence of the K-d scattering length on two models of [Formula: see text] interaction, providing one or two poles for the Λ(1405) resonance. The [Formula: see text] system is described by coupled-channels Faddeev equations in AGS form. The two-body [Formula: see text] interaction models reproduce all existing experimental data on K-p scattering and K-p atom level shift. The comparison with several approximations, commonly used for such calculations, was done.
