Abstract

The structure of the three-body nnΛ system, which has been observed recently by the HypHI Collaboration, is investigated taking ΛN-ΣN coupling explicitly into account. The YN and NN interactions employed in this work reproduce the binding energies of HΛ3, HΛ4, and HeΛ4. We do not find any nΛ3 bound state, which contradicts the interpretation of the data reported by the HypHI Collaboration.
