Open questions in hypernuclear structure and decays

The authors outline the current status of knowledge of the structure and weak decays of Λ hypernuclei. To make significant progress, good energy resolution and the ability to perform coincidence experiments are required. This in turn requires secondary beams of pions and kaons of high intensity and quality, matched with the appropriate detection systems. Considerable progress could be made at existing facilities, such as the Brookhaven AGS, with the addition of new spectrometers (probably old ones moved from elsewhere). In particular, there are prospects for studying S = -2, (mixed) Ξ and ΛΛ hypernuclear systems
