Geant4 hadronic physics status and validation for large HEP detectors
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 techniques facilitate the use of hadronic final states, and have
been developed for many years. We will give a brief overview of the physics
underlying hadronic shower simulation, discussing the three basic types of
modeling; data driven, parametrization driven, and theory driven modeling at
the example of Geant4. We will confront these different types of modeling with
the stringent requirements posed by the LHC experiments on hadronic shower
simulation, and report on the current status of the validation effort for large
HEP applications. We will address robustness, and CPU and physics performance
evaluations.Comment: Computing in High Energy and Nuclear Physics, La Jolla, California,
