Qualification, Performance Validation and Fast Generative Modelling of Beam Test Calorimeter Prototypes for the CMS Calorimeter Endcap Upgrade

After the calibration of the energy scale in the previous chapter, the reconstructed calorimeter hits correspond to localised measurements of the energy density of the recorded particle showers. Calorimeter hits of the same event can be visualised using event displays like in Fig. 10.1. They are the basis for the performance validation of the silicon-based HGCAL prototype to reconstruct the properties of the incident particles which is studied in this chapter.
