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

Abstract

Faddeev calculations of hypertriton (${}_{\Lambda }^3$H) 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 ${}_{\Lambda }^3$H.
