Description
Particle flow calorimetry builds on the high precision of the tracking system with high granularity in the calorimeter that can distinguish the source of energy depositions. The electromagnetic calorimeter (ECal) plays a key role in this technique. Monolithic Active Pixel Sensors (MAPS) employed in the ECal, with sub-mm^2 pixels and sub-nanosecond timing, offer the potential for extremely good performance in this role. This opportunity builds on the development of the optimized MAPS for tracking, the NAPA (NAnosecond timing Pixel for large Area sensors) program of compact timing pixel front ends optimized for the low-power operation needed in large-area detectors. The unprecedented granularity along with excellent timing of this approach will be used for hadron jet resolution improvement, including through optimization based on pattern recognition analysis using AI approaches.
