Abstract

Characteristics of the quasi-bound state in the K^- 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 KNN and πΣN were performed using different models of the ΣN and πN 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 KNN - πΣN - πΛN were performed.
