摘要
采用多元统计理论中的判别分析法处理北京谱仪中的e、π、μ分辨问题.介绍了判别分析法的基本原理,导出了用于分辨粒子的非标准判别函数,给出了e、π、μ的判别效率,并与常用方法所得的结果作了比较。
The discriminant analysis method in Multivariate Statistical Theory is used to handle e,π,μ separation in BES.The principle of the discriminant analysis method is described,the unstandardized discriminant functions(responsible for particle separation)are derived,the discriminant efficiencies for e,π,μ are given and the results are compared with those obtained from conventional way.
