Faddeev Calculation of Hypertriton Including with YNN Three-Body Force

Calculations have been performed for the Faddeev three-body equations of Hypertriton using the SMS chiral potential for NN interactions, the Jülich-Bonn NLO19 chiral potential for YN interactions, and the YNN three-body force as inputs. For the YNN three-body force, not only a 2𝜋 exchange type but also 1𝜋 exchange and contact types were adopted. Partial wave expansion was performed to examine the effects of each type. It is understood that in chiral NLO order, it is not possible to determine the low-energy coefficients (LECs) of the three-body force. However, the range dependence of the high momentum cutoff is examined.
