N2 - New Faddeev-Yakubovsky calculations for light ΛΛ hypernuclei are presented in order to assess the self-consistency of the ΛΛ-hypernuclear binding-energy world data and the implied strength of the ΛΛ interaction, in the wake of recent experimental reports on ΛΛ4H and ΛΛ6He. Using Gaussian soft-core simulations of Nijmegen one-boson-exchange model interactions, the Nijmegen soft-core model NSC97 simulations are found close to reproducing the recently reported binding energy of ΛΛ6He, but not those of other species. For stranger systems, Faddeev calculations of light Λξ hypemuclei, using a simulation of the strongly attractive ΛΞ interactions due to the same model, suggest that ΛΞ6He marks the onset of nuclear stability for Ξ hyperons.
