Faddeev calculations with the incorporation of a 2 pi-exchange Lambda NN three-baryon force are performed to determine the separation energy of hypertriton, H-3(A). Repulsive contributions of the three-baryon force, on the order of 20 keV, are found depending on the NN interactions used. This effect is significant compared to the small separation energy of H-3(A).
Faddeev calculations of hypertriton (H-3(A)) separation energy are performed, incorporating 2 pi-exchange Lambda NN three-baryon force. Repulsive contributions of the three-baryon force in the order of 20 keV are found, depending on the NN interactions employed. The effect is not negligible compared with the small separation energy of H-3(A).
