Improvements on the particle identification with dead cell and side leakage corrections for the electromagnetic calorimeter of the Alpha Magnetic Spectrometer

Background The electromagnetic calorimeter (ECAL) of the Alpha Magnetic Spectrometer (AMS-02) measures the energy of electrons/positrons and separates them from protons. Currently, there are five dead cells in the ECAL which affect the reconstructed energy of particles. The particle identification power of the ECAL decreases when particles pass through these dead cells or close to the ECAL border.
