Loosely bound hyperons in the SU(3) Skyrme model.

/ Abstract
Hyperon pairs bound in deuteronlike states are obtained with the SU(3) Skyrme model in agreement with general expectations from boson exchange models. The central binding from the flavor-symmetry-breaking terms increases with the strangeness contents of the interacting baryons whereas the kinetic nonlinear [sigma]-model term fixes the spin and isospin of the bound pair. We give a complete account of the interactions of octet baryons within the product approximation to baryon number [ital B]=2 configurations.
