Contributions of $2\pi$-exchange, $1\pi$-exchange, and contact three-body forces in NNLO ChEFT to ${}_{\Lambda }^3$H

M. Kohno, H. Kamada, K. Miyagawa

Faddeev calculations of hypertriton (${}_{\Lambda }^3$H) separation energy are performed, incorporating all next-to-next-to-leading-order $\Lambda$NN three-body forces (3BFs) in chiral effective fi…
