Hadron interactions in lattice QCD

Understand

Progress on the potential method, recently proposed to investigate hadron interactions in lattice QCD, is reviewed.

• The strategy to extract the potential in lattice QCD is explained in detail.
• The method is applied to extract $NN$ potentials, hyperon potentials and the meson-baryon potentials.
• A theoretical investigation is made to understand the origin of the repulsive core using the operator product expansion.
