Physics process validation of Geant4 (Draft)
نویسنده
چکیده
We have investigated the validity of our simulator. The validation item that we have already performed are summarized as follows. 1. Whether the energy loss distribution follows the Landau’s distribution. • thin absorber of Silicon 2. Whether the energy loss along per unit length follows the formula of Bethe-Bloch for protons. • thick absorber of Silicon • thick absorber of Lead 2 Landau’s distribution

Validation of Geant4 and Fluka Hadronic Physics with Pixel Test-Beam Data
In this note we present an update of the validation of Geant4 hadronic physics against the ATLAS pixel 2001 test-beam data. Furthermore, we also report the comparison with Fluka simulation, using the same Geant4 geometry, navigation and digitization.
متن کاملExperimental quantification of Geant4 PhysicsList recommendations: methods and results
The Geant4 physics lists package encompasses predefined selections of physics processes and models to be used in simulation applications. Limited documentation is available in the literature about Geant4 pre-packaged PhysicsLists and their validation. The reports in the literature mainly concern specific use cases. This paper documents the epistemological grounds for the validation of Geant4 pr...
متن کاملRecent improvements on the description of hadronic interactions in Geant4
We present an overview of recent improvements of hadronic models in Geant4 for the physics configurations (Physics Lists) relevant to applications in high energy experiments. During last year the improvements have concentrated on the study of unphysical discontinuities in calorimeter observables in the transition regions between the models used in Physics Lists. The microscopic origin of these ...
متن کاملValidation of spallation neutron production and propagation within Geant4
Using simulations to understand backgrounds from muon-induced neutrons is important in designing next-generation low-background underground experiments. Validation of relevant physics within the Geant4 simulation package has been completed by comparing to data from two recent experiments. Verification focused on the production and propagation of neutrons at energies important to underground exp...
متن کاملPhysics Validation of LHC Simulations
A review of the strategy and the results for the physics validation of Geant4 and Fluka detector simulation engines for LHC applications is presented. The main focus is on hadronic physics, where most of the efforts are currently concentrated. In particular, comparisons between simulation and test-beam data for the most relevant calorimeter observables, for different experiments and detector te...
