The LambdaQ-LambdaQ Potential
Daniel Arndt, Silas R. Beane, Martin J. Savage
Abstract
Lattice QCD simulations of the potential between two baryons, each containing a heavy quark and two light quarks, such as the LambdaQ-LambdaQ potential, will provide insight into the nucleon-nucleon interaction. As one-pion exchange does not contribute to the LambdaQ-LambdaQ 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 LambdaQ-LambdaQ potential in QCD and in partially-quenched QCD in the low-energy effective field theory.
