On Electron and Pion Identification using a Multilayer Perceptron in the Transition Radiation Detector of the CBM Experiment

Cover Page

Abstract


The problem of pion-electron identification based on their energy losses in the transition radiation detector (TRD) is considered in the frame of the CBM experiment. For particles identification an artificial neural network (ANN) was used, a multilayer perceptron being realized in JETNET and ROOT packages. It is demonstrated that, in order to get correct and comparable results, it is important to define the network structure correctly. The recommendations for such a selection are given. In order to achieve an acceptable level of pions suppression, the energy losses need to be transformed to more effective variables.
