摘要：
The exclusive decays of chi(c0) into multi-body B (B) over bar MM(B:baryon, M:meson) are investigated based on the SU(3) symmetry. The transitional amplitudes of chi(c)0 -> B (B) over bar -> B (B) over bar MM are given in terms of the isospin coupling constant. Based on these amplitudes, it is found that N* resonances make a relatively large contribution to the chi(c0) -> N (N) over bar pi pi, which might serve as a channel to study N* resonance in data analysis.
