| 摘 要： | 使用有效拉氏量法，我们对五个有趣的重子衰变道提供分拨振幅（PWA）及其衰变宽度。还有，通过粒子数据表上分支比（Branching ratio）进行拟合的，我们计算了核子-核子-介子耦合常数。

| Abstract: | By using effective Lagrangian method, we provide Partial Wave Amplitudes（PWA） and decay width for five interesting exotic baryon decay channels. And, we also calculate the coupling constants for the nucleon-nucleon-meson by using the branching ratios from particle data group（PDG）. |
