An algorithm has been developed for the GEANT4 Monte-Carlo package for the efficient computation of screened Coulomb interatomic scattering. It explicitly integrates the classical equations of motion for scattering events, resulting in precise tracking of both the projectile and the recoil target nucleus. The algorithm permits the user to plug in an arbitrary screening function, such as Lens-Je...

We discuss several features of hadronic showers recorded in the high granularity CALICE Si-W ECAL and scintillator-tile HCAL and confront them with several Geant4 physics models. The first measurements of the time-structure of hadronic showers in a tungsten scintillator calorimeter are presented. The high granularity of the CALICE calorimeters allows a software compensation which improves the e...
A set of physics processes has been developed in the Geant4 Simulation Toolkit to describe the electromagnetic interactions of photons and electrons with matter down to 250 eV. Preliminary comparisons of the models with experimental data show a satisfactory agreement.

A new Geant4 physics list is prepared for nuclear physics applications in the domain dominated by spallation. The C++ translation of original Fortran INCL intra-nuclear cascade and ABLA fission/de-excitation codes are used in the physics list. The INCL model prepared is well established for targets heavier than Aluminium and projectile energies from ∼ 150 MeV up to 2.5 GeV ∼ 3 GeV. Validity of ...
