Abstract
Highlights of ΛΛ emulsion events are briefly reviewed. Given three accepted events, shell-model predictions based on p-shell Λ hypernuclear spectroscopic studies are shown to reproduce \(B_{\Lambda\Lambda}({_{\Lambda\Lambda}^{~10}{\rm Be}})\) and \(B_{\Lambda\Lambda}({_{\Lambda\Lambda}^{~13}{\rm B}})\) in terms of \(B_{\Lambda\Lambda}({_{\Lambda\Lambda}^{~~6}{\rm He}})\). Predictions for other species offer judgement on several alternative assignments of the \(_{\Lambda\Lambda}^{~13}{\rm B}\) KEK-E176 event, and on the assignments \(_{\Lambda\Lambda}^{~11}{\rm Be}\) and \(_{\Lambda\Lambda}^{~12}{\rm Be}\) suggested recently for the KEK-E373 HIDA event. The predictions of the shell model, spanning a wide range of A values, are compared with those of cluster models, where the latter are available.
