Description
The energy calibration of calorimeters at collider experiments, such as the ones at the CERN Large Hadron Collider, is of primary importance. In this seminar, a novel calibration procedure, in that it calibrates every individual detector cells belonging to a particle shower, is presented. The method bypasses some of the difficulties that exist in more standard approaches when calibrating finely segmented calorimeters. It is implemented using differentiable programming. Simulated energy deposits in the electromagnetic section of a high-granularity calorimeter are used to study the method and demonstrate its performance. It is shown that the method is able to correct for biases in the energy response; the convergence of the algorithm is discussed.
