Improvements of the fast simulation of the CMS detector — •Maximilian Knut Kiesel — 1. Physikalisches Institut B, RWTH Aachen University

In todays experimental elementary particle physics, a reliable simulation of particle interactions is a key aspect. The interactions of particles from high energy collisions and their decay products with the CMS detector can be simulated using the GEANT4 framework. This approach is precise but time-consuming, therefore a faster simulation of the detector is used in several analyses.

In this talk, this faster simulation is discussed, focusing on the simulation of particles transversing the electromagnetic calorimeter. Furthermore, the challenges for the fast simulation in the next run period of the LHC are discussed and improvements to the simulation are presented.
