Abstract

We study the Σ*Δ interaction in the chiral SU(3) quark model and in the extended chiral SU(3) quark model. In these two models, the shortrange interaction mechanism are totally different, one is from the onegluon exchange and another is from the vector meson exchange. The possible reasons of forming strangeness -1 bound states are given. Comparisons between the cases with and without quark exchange effect are made. The results show the quark exchange effect does give attractions to (Σ*Δ)ST=0 52 and (Σ*Δ)ST=3 12 systems, which means the special symmetry is important. Also, we make some analysis on chiral field effect, our results show that the σ exchange dominantly provides the attractive interaction for these two states.
