Long-Range $N-J/\ddot{I}ˆ$ Interaction from an Operator Product Expansion Perspective

Seokwoo Yeo, In Woo Park, Su Houng Lee

A recent lattice QCD study has shown that the $N-J/\ddot{I}ˆ$ potential is attractive at all distances, and its long-range tail is well described by two-pion exchange. Here, we study to w…
