Abstract:

The bound state of the hypertriton is investigated by solving the Faddeev equation in the coordinate space. A realistic local Λ-nucleon potential derived from the meson-theoretical point of view is proposed by parametrizing to reproduce the phase shift obtained by Λ-nucleon scattering parameters, and for the internucleon interaction the Reid soft core potential including a tensor force is used.
Our calculated result of the Λ-separation energy for the ground (J=1/2) state of the hypertriton is in the error range of recent experimental values. On the other hand, it is confirmed by this method that a possible excited (J=3/2) state cannot be bound.
