Abstract

The Faddeev equations for the hypertriton are solved precisely using the Nijmegen hyperon-nucleon and realistic NN interactions. The hypertriton turns out to be bound at the experimental value. Thereby the Λ-Σ conversion is crucial. States of the Λ(Σ)NN system with quantum numbers (T,J) different from (0,1/2) are not bound. We visualized properties of the hypertriton wave function in various ways.
