摘要：
Geant4 [1] provides a software toolkit for the simulation of particles through matter. It has wide range of applicability, ranging from high-energy particle physics to space science. The physics description of Geant4 is in a constant process of improvement and validation. In this work a new relativistic Bremsstrahlung model is introduced. The key feature is a consistent description of matter effects, esp. the Landau-Pomeranchuk-Migdal (LPM) effect. The LPM effect will be of paramount importance for experiments at modern high-energy colliders, esp. the LHC, as well as in astroparticle physics applications.
