Methods of e/π Identification with the Transition Radiation Detector in the CBM Experiment

Cover Page

Abstract


A problem of e/π identification using n-layered transition radiation detector (TRD) in the CBM experiment is considered. With this aim, we elaborated algorithms and implemented various approaches. We discuss the characteristic properties of the energy losses by electrons and pions in the TRD layers and special features of applying artificial neural networks (ANN) and statistical methods to the problem under consideration. A comparative analysis is performed on the power of the statistical criteria and ANN.
