Abstract
The coupled Λ Λ nn-Ξ- pnn system was studied to investigate whether the inclusion of channel coupling is able to bind the Λ Λ nn-Ξ- system. We use a separable potential three-body model of the coupled Λ Λ nn-Ξ- pnn system and a variational four-body calculation with realistic interactions. Our results exclude the possibility of a Λ Λ nn bound state by a large margin. Instead, we found a Ξ- t quasibound state above the Λ Λ nn threshold.
