Abstract:
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.
