摘要：
Lattice QCD simulations of the potential between two baryons, each containing a heavy quark and two light quarks, such as the Lambda(Q)Lambda(Q) potential, will provide insight into the nucleon-nucleon interaction. As one-pion exchange does not contribute to the Lambda(Q)Lambda(Q) potential, the long-distance behavior is dominated by physics that contributes to the intermediate-range attraction between two nucleons. We compute the leading long-distance contributions to the Lambda(Q)Lambda(Q) potential in QCD and in partially-quenched QCD in the low-energy effective field theory.
