In this work we report on recent improvements in the electromagnetic (EM) physics models of Geant4 and new validations of EM physics. Improvements have been made in models of the photoelectric effect, Compton scattering, gamma conversion to electron and muon pairs, fluctuations of energy loss, multiple scattering, synchrotron radiation, and high energy positron annihilation.

/Geant4 electromagnetic physics working groups
In this work we present recent progress in Geant4 electromagnetic physics modelling, with an emphasis on the new refinements for the processes of multiple and single scattering, ionisation, high energy muon interactions, and gamma induced processes. The future LHC upgrade to 13 TeV will bring new requirements regarding the quality of electromagnetic physics simulation: energy, particle multiplicity, and statistics will be increased. [...]

Report on G4‐Med, a Geant4 benchmarking system for medical physics applications developed by the Geant4 Medical Simulation Benchmarking Group
/ Arce, P (Madrid, CIEMAT) ; Bolst, D (Wollongong U.) ; Cutajar, D (Wollongong U.) ; Guatelli, S (Wollongong U.) ; Le, A (Wollongong U.) ; Rosenfeld, A B (Wollongong U.) ; Sakata, D (Wollongong U.) ; Bordage, M‐C (CRCT, Toulouse) ; Brown, J M C (KIN, Delft) ; Cirrone, P (INFN, LNS) et al.
Geant4 is a Monte Carlo code extensively used in medical physics for a wide range of applications, such as dosimetry, micro‐ and nano‐ dosimetry, imaging, radiation protection and nuclear medicine. Geant4 is continuously evolving, so it is crucial to have a system that benchmarks this Monte Carlo code for medical physics against reference data and to perform regression testing. [...]
