Description
It takes two nucleons to bind a Lambda hyperon, and perhaps as many as three nucleons to bind two Lambda hyperons. In my talk I will review few-body calculations which are relevant for deciphering the onset of binding in Lambda hypernuclei and in Lambda-Lambda hypernuclei.
I will also discuss the onset of binding for Xi hyperons, stabilizing them against the free-space
conversion Xi + N --> Lambda + Lambda, which may require a core of two protons, two neutrons
and two Lambda hyperons. The Physics implications on the stability of strange hadronic matter
will be discussed.
