Description
An overview of the current status of electromagnetic physics (EM) of the Geant4 toolkit is presented. Recent improvements are focused on the performance of large scale production for LHC and on the precision of simulation results over a wide energy range. Significant efforts have been made to improve the accuracy and CPU speed for EM particle transport. New biasing options available for Geant4 EM physics are presented. It is shown that the performance of the EM sub-package is improved. We will report extensions of the testing suite for high statistics validation of EM physics. It includes validation of multiple scattering, bremsstrahlung and other models. The precision of simulation results on the shape of EM showers is discussed in detail. It includes the validation of both high and low energy components of a shower. Cross checks between standard and low-energy EM models have been performed using evaluated data libraries and reference benchmark results.
