Description
We have been performing calculations [1] using the SMS chiral potential [2] for NN interactions, the Juelich NLO19 chiral potential [3] for YN interactions, and the YNN three-body force [4] as inputs for the Faddeev three-body equations of Hypertriton. For the YNN three-body force, not only a two-pion exchange type but also one-pion exchange and contact types were adopted. Partial wave expansion [5] was performed to examine [6] the effects of each type. It is known that in chiral NLO order, it is not possible to determine the low-energy coefficients (LECs) of the three-body force, but the range dependence of the high momentum cutoff is examined.
