Abstract
Using separable potential equations to model the T=0, J=(1/2 ΛNN three-body system, we explore the effects of ΛN-ΣN coupling in the ground state of the hypertriton. Explicit ΛN-ΣN coupling in the hyperon-nucleon interaction is shown to play a significant role, even in this lightly bound system. When the ΣN channel is formally eliminated, the dispersive energy dependence of the resulting ΛN effective interaction is repulsive whereas the resulting ΛNN three-body force is attractive.Keywords
