The nucleon-nucleon force from skyrmions

The applications of Skyrmions to the derivation of the nucleon-nucleon force is reviewed with attention to the use of the product ansatz, additional terms in the Lagrangian, baryon resonance admixtures, the instanton ansatz, dilatons, and exact two- or three-dimensional solutions for the B = 2 system in order to find the sources of attraction in the central and spin-orbit potentials. We also discuss extensions to two-baryon systems with nonzero strangeness and address possible insights into the behavior of the nucleon in nuclei achieved from the Skyrmion approach.
