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 \(\bar{K}NN\) and \(\pi \varSigma N\) were performed using different models of the \(\varSigma N\) and \(\pi N\) interactions to study the influence of these “less important” interactions on the three-body result. In addition, dynamically exact three-body Faddeev-type AGS calculations with three coupled particle channels \(\bar{K}NN - \pi \varSigma N - \pi \varLambda N\) were performed.
