In the past years, the chiral SU(3) quark model has achieved success. In this model, the nonet pseudo-scalar meson exchanges and the nonet scalar meson exchanges are considered in describing the medium-and long-range parts of the interactions, and the one gluon exchange describe the short-range repulsion.

过去几年来，手征SU(3)夸克模型已经取得了相当的成功，应用该模型统一地解释了重子基态的能谱，核子-核子以及核子-超子散射过程，并由此预言了实验上可能存在的双重子束缚态。

In the chiral SU(3) quark model, we use the coupling between quarks and nonet scalar meson fields and nonet pseudo-scalar meson fields to describe the medium and long range interactions, and use one gluon exchange to describe the short range interaction. In the extended chiral SU(3) quark model, besides the nonet pseudo-scalar meson fields and the nonet scalar meson fields, the coupling between vector meson fields and quarks is also considered, the short range interaction can be dominately described by vector meson exchange. We investigate the nucleon-hyperon interaction in the extended chiral SU(3) quark model and study the S-wave phase shifts of N-Λ and N-Σ systems. Comparing to the results in chiral SU(3) quark model, we find that the short-range interaction could be described either by the one-gluon exchange or vector meson exchange.
