| Popis: | 107 This study proposes a particle identification discriminator analysis which based on the new-architected detector module with high spatial and temporal resolution com- posed of silicon-pads which was tested in 2016 CERN H2 testbeam campaign. The linearity and energy resolution measurements of the detector is initially obtained using the testbeam data of electron energies of 20, 32, 70, 100, 150, 200, 250GeV, pion energy of 125GeV while the longitudinal and transverse shower profiles are verified from the data/MC comparison. The validity of the discriminator two-point-correlation variable is then verified under the requirements of the alignment of testbeam with the center of the first layer within 2mm × 2mm window and the profile of the variable is acquired at which the shower maximum of the event is developed. Eventually, the distinctive signatures of electron and pion shower shape are presented by comparing the MC profiles, showing the disparity behavior in HGCAL and suggesting its potential for further application. |
