Abstract: We perform the quenched lattice QCD analysis on the nuclear force (baryon‐baryon interactions). We employ 203 × 24 lattice at β = 5.7 (a ≃ 0.19 fm) with the standard gauge action and the Wilson quark action with the hopping parameters κ = 0.1600, 0.1625, 0.1650, and generate about 200 gauge configurations. We measure the temporal correlators of the two‐baryon system which consists of heavy‐light‐light quarks. We extract the inter‐baryon force as a function of the relative distance r. We also evaluate the contribution to the nuclear force from each “Feynman diagram” such as the quark‐exchange diagram individually, and single out the roles of Pauli‐blocking effects or quark exchanges in the inter‐baryon interactions.
