Hadronic Shower Models in Geant4 - the Frameworks

J.P. Wellisch,

Speaker: Johannes Peter Wellisch

  Optimal exploitation of hadronic final states played a key role in successes of all recent collider experiment in HEP, and the ability to use hadronic final states will continue to be one of the decisive issues during the analysis phase of the LHC experiments. Monte Carlo programs like geant4 facilitate the use of hadronic final states, and have been developed for many years.
  We will give an overview on the Object Oriented frameworks for hadronic generators in geant4, and the physics models underlying hadronic shower simulation, discussing the three basic types of modelling; data driven, parametrisation driven, and theory driven modelling, and their realization as an Object Oriented component system in geant4. We will in particular address the level of extendibility that can and has been achieved by our russian doll approach to Object Oriented design, and the role and importance of the frameworks in this component system.
