*Possibility of New Light Hypernuclei*

The spectroscopy and production mechanisms of light hypernuclei with strangeness -1 or -2 are
revisited. There is already an abundant literature of the subject, but the recent approaches to
inter-hadronic forces offer new possibilities of binding, for instance, a neutral state made of two
neutrons and two hyperons. For a given set of scattering lengths, the existence of such a Borromean
bound state depends crucially on the value of the effective range parameter for the hyperon-hyperon
and hyperon-neutron interaction.
