Abstract：
Branching ratios of cross section for pp annihilation into two various meson processes are calculated by using the one-gluon-exchange quark-antiquark annihilation potential model. The results are compared with the experimental data and other theoretical values. For the processe pp→π⁺π^－, the cross section as a function of incident momentum of p is also studied and it is in agreement with the measured result.
