One-versus two-pole (K)over-bar N-pi Sigma potential: K(-)d scattering length
Original language description
We investigated the dependence of the K(-)d scattering length on models of the (K) over barN interaction with one or two poles for the Lambda(1405) resonance. The (K) over bar NN-pi Sigma N system is described by coupled-channel Faddeev equations in Alt-Grassberger-Sandhas form. Our new two-body (K) over bar N-pi Sigma potentials reproduce all existing experimental data on K-p scattering and kaonic hydrogen atom characteristics. New models of the Sigma N-Lambda N interaction were also constructed. Comparison with several approximations, usually used for scattering length calculations, was performed.
