利用单粒子交换方法 ,研究了D介子衰变到两个赝标粒子中的末态相互作用 .通过实验数据中抽取的强相角来分析末态相互作用的效应
The single-particle exchange method was used to study the final state interaction of decaying D mesons to two pseudoscalar particles. The effect of the final state interaction was analyzed by the strong phase angle extracted from the experimental data
