Studies on High Granularity Calorimeter Upgrade to the Compact Muon Solenoid Experiment at CERN*

The goal of my research is to optimize the design of High Granularity Calorimeter (HGCAL) for Jet and MET measurements in preparation for the High Luminosity upgrade to the Compact Muon Solenoid (CMS) Experiment during Long Shutdown 3, beginning in 2024. This upgrade is crucial to overcome hardware radiation tolerance issues and to produce better structure analysis and particle identification. To do so we performed several studies involved software to simulate particle collisions with different HGCAL detector geometries and analyzed the resulting histograms. The studies revealed bugs in detector geometry configuration and tested the efficiency of the simulations to produce accurate particle collision results. These studies are a continuation of software development to effectively construct the most useful detector design for the next CMS upgrade.
