Description
In this presentation we review recent updates in Geant4 electromagnetic (EM) physics sub-libraries in view of Run4 and other collider experiments. The evolution of EM sub-libraries is performed in order to make code more robust, compact, and compatible with requirements of Run4 detectors at LHC and other future collider experiments. A significant role in this respect is taken by the G4HepEm sub-library, which is external to Geant4 but fully compatible and may be used as an alternative to the default EM configuration. Results with this library are with high accuracy in statistical agreement with the default EM physics. A new development on simulation of EM physics in bending crystals will be discussed as well as application of these methods to various components of particle accelerator. Additionally, EM physics group develop new approaches for simulation of X-Ray production processes and X-Ray interaction with elements of machine and their surfaces. A new design for Cerenkov and Scintillation processes is introduced to the recent Geant4 version 11.4. A new method how combine condense history standard processes and track structure code for the Geant4-DNA project will be presented.
