Hypertriton as a test of theoretical hyperon-nucleon potentials

A separable potential approximation to recent meson theoretic hyperon-nucleon potentials is made such that the low energy scattering parameters are reproduced. The resulting charge asymmetric potentials describing the Λ-p and Λ-n singlet and triplet interactions are used in a Faddeev-type calculation of the hypertriton binding energy. One particular one-boson exchange potential model, having effective ranges greater than 3 fm, gives a reasonable binding.NUCLEAR STRUCTURE _Λ³H, Y-N potentials, separable potential three-body calculation, B_Λ.
