Title: "Reconstruction for the CMS High Granularity Calorimeter"

Speaker: Kevin Pedro, Fermilab
 

Abstract: The Phase 2 upgrade for the CMS detector will include a high granularity imaging calorimeter (HGCAL) in the endcap region. This calorimeter will be able to survive the high radiation environment of the High Luminosity LHC and perform in an environment with an average of at least 140 interactions per bunch crossing. The HGCAL is based on a detector design and reconstruction algorithms developed by the ILC detector collaborations ILD and CALICE. The feasibility of employing these algorithms in high-multiplicity events is dependent on advanced computational techniques, which will be discussed in detail. There are also interesting challenges in pattern recognition and shower reconstruction when using imaging calorimetry in events with occupancies much higher than ILC or CLIC. Current simulated performance results and future prospects will also be discussed.
