Faddeev Calculation of ${}_{\hat{I}}{›}^3$H incorporating 2π-exchange $\hat{I}›$NN Interaction

Abstract

Faddeev calculations of hypertriton (${}_{\hat{I}}{›}^3$H) separation energy are performed, incorporating $2\ddot{I}€$-exchange $\hat{I}›$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 ${}_{\hat{I}}{›}^3$H.
