Project Title: 
Crystal Calorimeter Calibration With Deep Learning

This research group is part of the CERN Large Hadron Collider (LHC) CMS collaboration. This group's research focus is on measurements of the Higgs boson's properties and in the search for anomalous interactions using high energy photons.

The CMS experiment has  ~72,000 lead tungstate crystals equipped with photodetectors in order to detect and measure high energy electrons and photons produced in collisions at the LHC. The intercalibration of these crystals, where the response is made uniform across the detector, is needed for all measurements made with electrons and photons, and the quality of the intercalibration determines the precision of these measurements. The workflow of the intercalibration proceedure is highly complex, requires many intermediate steps, and generally takes more than a year of dedicated effort to fully validate. The group is investigating porting the intercalibration process to one that uses deep learning techniques in order to achieve the intercalibration more rapidly.
