The purpose of this study is to explore the interaction between various particles and study their dynamic relationships by analyzing these two processes. Specifically, this study will focus on the interaction between π- and π0 and protons, as well as the dynamic relationship between K+ and K- particles. In addition, the characteristics of XCJ mesons in physics will also be studied.The method used in this study is empirical analysis, which analyzes and studies experimental data. The specific research methods include screening and processing the data of XCJ→Pnπ-(π0)+C.C. and Jψ→PPφ processes to obtain their distribution rules and characteristics. Then, the uncertainty and error in the data are analyzed, and relevant statistical methods are used to process the data. Finally, through analysis and comparison of experimental results, the dynamic 精品文档---下载后可任意编辑relationship and interaction law between various particles are obtained.The expected result is that through this study, there will be a deeper understanding of the properties of XCJ mesons, a more in-depth understanding of the interaction between π- and π0 and protons, and the dynamic relationship between K+ and K- particles. At the same time, it will provide a foundation and reference for future research in related fields.Keywords: BESⅢ; XCJ meson; dynamic relationship; interaction
