Description

We have developed and studied the statistical multidimensional combined algorithm for selecting the electron and pion events. The algorithm is based on different spatial electromagnetic and hadronic shower developments. The method has been tested on the basis of the experimental data of the ATLAS tile iron-scintillator hadronic calorimeter exposed to the electron and pion beams of energies from 10 to 300 GeV of the CERN SPS. The results of the investigation have shown high efficiency (at the level of 99.8%) of the event separation. This algorithm can be used for data analysis from the modern combined calorimeters like the ATLAS, CMS detectors at the LHC and the CDF, D0 at the TEVATRON
