Reconstructing HL‑LHC events in the CMS endcap calorimeter

Abstract: The CMS Collaboration is preparing to replace its endcap calorimeters for the HL-LHC era with a high-granularity calorimeter (HGCAL). The design uses silicon sensors as active material in the regions of highest radiation and plastic scintillator tiles equipped with silicon photomultipliers (SiPMs), in the less-challenging regions. The unprecedented transverse and longitudinal readout segmentation is intended to facilitate particle identification, particle-flow reconstruction and pileup rejection. I will describe the reconstruction framework being developed and some of the methods being explored.
