Coupled-channel ${\Lambda }_c{K}^{+}-p{D}_s$ Interaction in Flavor $\text{SU}\left(3\right)$ Limit of Lattice QCD

Faisal Etminan, Kenji Sasaki, Takashi Inoue

We study $S$-wave interactions in the $I\left(J^p\right)=1/2\left(1/2^{-}\right)$ ${\Lambda }_c{K}^{+}-p{D}_s$ system on the basis of the coupled-channel HAL QCD method. The potentials wh…
