A coherent framework for full, fast and parametric detector simulation for the FCC project [1.96 mb]
Zusammenfassung (Englisch)

The outstanding success of the physics program of the Large Hadron Collider (LHC), including the discovery of the Higgs boson, shifted the focus of part of the high energy physics community onto the planning phase for future collider projects. The FCC (Future Circular Collider) is a five year international design study to explore post-LHC possibilities. Hadron and electron-positron based collider technologies are considered as potential LHC successor project branches. Common to both branches is the need of a coherent software framework, in order to carry out simulation studies to establish the potential physics reach or to test different technology approaches. Detector simulation is a particularly necessary tool needed for both, design studies for different detector concepts and the establishment of relevant performance parameters. In addition, it allows to generate data as input for the development of reconstruction algorithms needed to cope with the expected future environments.A coherent framework will be presented, that combines full, fast and parametric detector simulation embedded in the Gaudi framework and based on the FCC Event Data Model. Detector description is based on DD4hep and the dierent simulation approaches are centrally steered through the Geant4 simulation. A geometry for reconstruction was integrated into the framework. This geometry will also be used for fast simulation. The DD4hep geometry is automatically translated into the different geometries needed by the different simulations. A prototype example of a simple tracking detector is demonstrated for the different simulation approaches and the detector geometries together with the materials are compared. Furthermore, a potential work how to use full simulation based on Geant4 and fast simulation techniques alongside is presented and the results are compared.
