Abstract

The Geant4 Collaboration is leading a long-term validation program to port calorimeter test-beam simulations and results into geant-val, the Geant4 validation and testing suite. New results including Geant4 regression testing and physics list comparison are presented and discussed. Moreover, the new Geant4-to-FLUKA.CERN interface recently allowed detailed comparisons between the hadronic models in Geant4 and the FLUKA.CERN Monte Carlo codes. The interface is described and some geant-val results obtained with it are presented here for the first time.
