Abstract
A unified description of the hyperon-nucleon interaction consistent with the NN interaction is given in the RGM formulation of the SUs quark model, in which the full Fermi-Breit interaction with explicit flavor symmetry breaking is incorporated. The medium-range central and long-range tensor components of the hyperon-nucleon interaction are augumented by the effective meson-exchange potentials generated from the scalar-meson nonet and ;r and K mesons of the Nijmegen model-F. With two parameters determined from the deuteron binding energy and NN 'So phase shift, all the low-energy cross sections of the hyperon-nucleon interaction currently available are reasonably reproduced. The analysis of NN and ;I;+p systems is presented.
