Development of Future Electromagnetic Calorimeter Technologies and Applications for the Electron-Ion Collider with GEANT4 Simulations

The Electron-Ion Collider (EIC) is a future collider planned to be built at BNL in about decade. It will provide physicists with high luminosity and highly polarized beams wide range of nuclei species different energies, covering an extensive kinematic range. EIC physics goals include measuring the Generalized Parton Distribution (GPD) from Deeply Virtual Compton Scattering (DVCS) Meson Production (DVMP) experiments, performing precision 3D imaging structure, studying color confinement hadronization mechanisms, understanding spin structure proton. In order meet EIC, highresolution electromagnetic calorimeter (EMCAL) required measure electrons photons achieve good particle identification. We propose develop tungsten/shashlik (W/shashlik) EMCAL better readout configuration energy position resolution. this work, we present GEANT4 detector simulation results ofWand Pb shashlik study π 0 merging probability as function performance resolutions for ECCE design.
