Short-range YN interactions in the Quark Cluster Model
Abstract
A phenomenological model for the hyperon-nucleon interactions is constructed by using the quark cluster model approach to the short-distance baryon-baryon interactions. The model contains the SU(3) symmetric meson exchange interaction at large distances and the quark-exchange short-distance interaction. The main feature of the model is that strong channel dependences of the short range repulsions due to the quark model symmetry. It is pointed out that two channels, (, )= (1/2, 0) and (3/2, 1), of the S-wave sigma-nucleon interactions have extremely strong repulsions at short-distances.
