Geant4 Physics Developments and Validation

Geant4 Physics

The team at INFN Genova has been involved in various projects of Geant4 physics modelling and validation since the RD44 phase.
The activity in the RD44 phase and in the early years of Geant4 public distribution was focused on hadronic physics: the Pion Absorption at Rest and the Photon Evaporation models developed in RD44 not only have introduced new physics capabilities in Geant4, but also demonstrated for the first time mixed parameterized-theoretical  models in Geant4 hadronic physics design.
The Geant4 team at INFN Genova launched the development of Geant4 Low Energy Electromagnetic Physics, of the first models for micro/nano dosimetry simulation and of the first core of Geant4 models relevant to plasma physics.

The physics activity is currently pursued in the framework of the NANO5 Project.
