Supercomput.) ; Chappuis, Flore (Lausanne U.) ; Cirrone, Giuseppe Antonio Pablo (INFN, LNS ; Enrico Fermi Ctr., Rome) ; Desorgher, Laurent (Ecole Polytechnique, Lausanne) ; Dominguez, Naoki (San Francisco U.) ; Fattori, Serena (INFN, LNS) ; Guatelli, Susanna (Wollongong U.) et al.
AbstractA chemistry module has been implemented in Geant4‐DNA since Geant4 version 10.1 to simulate the radiolysis of water after irradiation. It has been used in a number of applications, including the calculation of G‐values and early DNA damage, allowing the comparison with experimental data. [...]

Implementation of the EPICS2017 database for photons in Geant4
/ Li, Zhuxin (CENBG, Gradignan) ; Michelet, Claire (CENBG, Gradignan) ; Incerti, Sébastien (CENBG, Gradignan) ; Ivanchenko, Vladimir (Tomsk State U. ; CERN) ; Novak, Mihaly (CERN) ; Guatelli, Susanna (Wollongong U.) ; Seznec, Hervé (CENBG, Gradignan)
This paper describes in detail the implementation of Geant4 Livermore electromagnetic physics models based on the EPICS2017 database for the low energy transport of photons. These models describe four photon processes: gamma conversion, Compton scattering, photoelectric effect and Rayleigh scattering. [...]

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. [...]

Geant4 electromagnetic physics progress
/ Ivanchenko, Vladimir (CERN ; Tomsk State U.) ; Bagulya, Alexander (Lebedev Inst.) ; Bakr, Samer (Wollongong U.) ; Bandieramonte, Marilena (CERN ; U. Pittsburgh (main)) ; Bernard, Denis (Ecole Polytechnique) ; Bordage, Marie-Claude (CRCT, Toulouse) ; Burkhardt, Helmut (CERN) ; Dondero, Paolo (Columbus Supercond., Genova) ; Grichine, Vladimir (Lebedev Inst.) ; Guatelli, Susanna (Wollongong U.) et al.
The Geant4 electromagnetic (EM) physics sub-packages are a component of LHC experiment simulations. During long shutdown 2 for LHC, these packages are under intensive development and we report progress of EM physics in Geant4 versions 10.5 and 10.6, which includes faster computation, more accurate EM models, and extensions to the validation suite.

Advances in modelling gold nanoparticle radiosensitization using new Geant4-DNA physics models
/ Engels, Elette (Wollongong U.) ; Bakr, Samer (Wollongong U.) ; Bolst, David (Wollongong U.) ; Sakata, Dousatsu (Wollongong U.) ; Li, Nan (Wollongong U.) ; Lazarakis, Peter (Wollongong U.) ; McMahon, Stephen J (Queen's U., Belfast) ; Ivanchenko, Vladimir (Tomsk State U. ; CERN) ; Rosenfeld, Anatoly B (Wollongong U.) ; Incerti, Sébastien (CENBG, Gradignan ; CENBG, Gradignan ; Bordeaux U.) et al.
Gold nanoparticles have demonstrated significant radiosensitization of cancer treatment with x-ray radiotherapy. To understand the mechanisms at the basis of nanoparticle radiosensitization, Monte Carlo simulations are used to investigate the dose enhancement, given a certain nanoparticle concentration and distribution in the biological medium.
