| 英文摘要 | The lepton identification is essential for the physics programs at high-energy frontier, especially for the precise measurement of the higgs boson. for this purpose, a toolkit for multivariate data analysis (tmva) based lepton identification (lich) has been developed for detectors using high granularity calorimeters. using the conceptual detector geometry for the circular electron-positron collider (cepc) and single charged particle samples with energy larger than 2 gev, lich identifies electrons/muons with efficiencies higher than 99.5% and controls the misidentification rate of hadron to muons/electrons to better than 1/0.5%. reducing the calorimeter granularity by 1-2 orders of magnitude, the lepton identification performance is stable for particles with e > 2 gev. applied to fully simulated eeh/mu mu h events, the lepton identification performance is consistent with the single particle case: the efficiency of identifying all the high energy leptons in an event, is 95.5-98.5%. |
