Abstract

Characteristics of the quasi-bound state in the K−ppK^- pp system strongly depend on the model of antikaon-nucleon interaction and weakly - on the nucleon-nucleon potential. In the present paper, dynamically exact Faddeev-type calculations with coupled KˉNN\bar{K}NN and πΣN\pi \Sigma N were performed using different models of the ΣN\Sigma N and πN\pi N interactions to study the influence of these "less important" interaction on the three-body result. In addition, dynamically exact three-body Faddeev-type AGS calculations with three coupled particle channels KˉNN−πΣN−πΛN\bar{K}NN - \pi \Sigma N - \pi \Lambda N were performed.
