Description

We revisit the spectroscopy and some production mechanisms of light hypernuclei with single or double strangeness. There is already an abundant literature on the subject [1-4], and we generally recover the published results. We first review the rigorous limits on the possibilities of “Borromean” binding, i.e., bound states whose subsytems and unbound, and discuss whether novel possibilities exist of critically-bound systems containing nucleons and hyperons. We stress the role of the the effective range when designing tool potentials that mimic more elaborate meson-exchange models fitting the data. Some production mechanisms involving deuteron beams and/or targets are investigated. [1]I.N. Filikhin and A. Gal, Phys.Rev.Lett., 89:172502, 2002. [2]H. Nemura, Y.
