Abstract：
The exclusive decays of χ_c0 into multi-body BBMM(B:baryon,M:meson)are investigated based on the SU(3) symmetry. The transitional amplitudes of χ_c0→BBMM 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 χ_c0→NNππ, which might serve as a channel to study N^* resonance in data analysis.
