Two- and three-body resonances in the $ar{K}$NN − πΣN system
One of the most important characteristics of a two-body interaction is existence and properties of its bound states or resonances. When the interaction is used in a few- or many-body calculation they also strongly influence the properties of the few- or many-body system. We investigate the depende...

| Summary: | One of the most important characteristics of a two-body interaction is existence and properties of its bound states or resonances. When the interaction is used in a few- or many-body calculation they also strongly influence the properties of the few- or many-body system. We investigate the dependence of the three-body resonance properties in the $ar{K}$NN system on the different models of $ar{K}$N interaction, providing one or two poles for Λ(1405) resonance. The $ar{K}$NN − πΣN system is described by coupled-channel Faddeev equations in AGS form, our two-body $ar{K}$N − πΣ interaction models reproduce all existing experimental data on K− p scattering and K− p atom level shift. |
