The baryon-baryon interaction in the SU(3) Skyrme model

Potentials among the octet and decuplet baryons are calculated under the product ansatz in the SU(3) Skyrme model. The potentials generally agree with conventional meson-exchange potentials at large distances. Some peculiality is, however, observed stemming from the commonly-used SU(3) quantization using rotational collective coordinates. The spin-isospin independent central potential is weakly attractive in intermediate range due to the strong chiral symmetry breaking term. The SU(3) model yields the isoscalar spin-dependent potential that does not appear in SU(2) models. (author)
