Abstract.

Using separable potentials for the \( \bar{K}N\) - \( \pi\Sigma\) interaction, we investigated four-body kaonic nuclear systems, such as \( K^{-}ppn\) and \( K^{-}K^{-}pp\) , with the Faddeev AGS method in the momentum representation. The Faddeev calculations are based on the quasi-particle method and the method of energy-dependent pole expansion was used to obtain the separable representation for the integral kernels in the three- and four-body equations. Different types of \( \bar{K}N\) - \( \pi\Sigma\) potentials based on phenomenological and chiral SU(3) approach are used and it was shown that the kaonic nuclear systems under consideration are tightly bound.
