Title: Possibility of new light hypernuclei

Abstract: 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.
