${\Xi }^{-}t$ quasibound state instead of $\Lambda \Lambda nn$ bound state

H. Garcilazo, A. Valcarce, J. Vijande

We study the coupled $\Lambda \Lambda nn-{\Xi }^{-}pnn$ system to check whether the inclusion of channel coupling is able to bind the $\Lambda \Lambda nn$ system. We use a separable potential three-body model of th…
