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, ad ditional terms in the Lagrangian, baryon resonance admixtures, the ins tanton ansatz; dilatons, and exact two- or three-dimensional solutions for the B = 2 system in order to find the sources of attraction in th e 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.
