O'Brienb, A.Rimoldid a CERN, Geneva, Switzerland b University of Edinburgh, Edinburgh, UK c Caltech, USA & Columbia University, USA d Dipartimento di Fisica Nucleare e Teorica dell’Universita’ di Pavia and INFN, Sezione di Pavia, Italy d Cavendish Laboratory, University of Cambridge, UK On behalf of the ATLAS collaboration Abstract The simulation software for the ATLAS Experiment at the Large Hadron Collider will be presented. It requires many components, from the generators that simulate the particle collisions, through packages simulating the response of the various detectors and triggers. All of these components come together under the ATLAS simulation infrastructure. This infrastructure will be discussed, including that supporting the detector description, interfacing the event generation, and combining the GEANT4 simulation of the response of the individual detectors. Also described are the tools allowing the software validation, performance testing, and the validation of the simulated output against known physics processes. The simulation has been used for large-scale production of billions of events on the LHC Computing Grid and now faces the ultimate challenge of real LHC collision data validation. Download 5.26 Kb.
