Identification of light leptons and pions in the electromagnetic calorimeter of Belle IINovosel, Anja (Avtor) Charan, Abtin Narimani (Avtor) Šantelj, Luka (Avtor) Ferber, Torben (Avtor) Križan, Peter (Avtor) Golob, Boštjan (Avtor) electromagnetic calorimeterparticle identificationconvolutional neural networkThe paper discusses new method for electron/pion and muon/pion separation in the Belle II detector at transverse momenta below 0.7 GeV/c, which is essential for efficient measurements of semi-leptonic decays of $B$ mesons with tau lepton in the final state. The method is based on the analysis of patterns in the electromagnetic calorimeter by using a Convolutional Neural Network (CNN).20232024-07-02 10:40:42Članek v reviji159153ISSN pri članku: 0168-9002DOI: 10.1016/j.nima.2023.168630COBISS_ID: 200863747sl
