Cm Electromagnetic Calorimeter

The CMS electromagnetic calorimeter (ECAL) is a crucial component of the CMS detector at the Large Hadron Collider, responsible for measuring the energy of electrons and photons. Current research focuses on improving ECAL data quality monitoring and particle reconstruction using machine learning techniques, particularly autoencoders and graph neural networks, to enhance anomaly detection, energy resolution, and the overall accuracy of physics analyses. These advancements are vital for maintaining and improving the performance of the CMS experiment, enabling more precise measurements and discoveries in high-energy physics.
