“…Contemporary and future experimental studies of anti-nucleus production require a knowledge of anti-nucleus interaction cross sections with matter which are needed to estimate various experimental corrections, especially those due to particle losses which reduce the detected rate. Because only a few measurements of these cross sections exist, they were calculated using the Glauber approach [152][153][154] and the Monte Carlo averaging method proposed in [155,156]. Two main considerations are used in the calculations: a parameterization of the amplitude of antinucleon-nucleon elastic scattering in the impact parameter representation and a parameterization of one-particle nuclear densities for various nuclei.…”

“…Dalkarov and V.A. Karmanov [11] showed that elastic and inelastic (with excitation of nuclear levels) antiproton scattering on C, Ca, and Pb nuclei are described quite well atp kinetic energies of 46.8 and 179.7 MeV within the approximation. The Glauber approach in the question was also used in many other papers.…”

On behalf of the Geant4 CollaborationAntiproton-proton, antiproton-nucleus and antinucleus-nucleus interactions are considered in Dual-Parton or Quark-Gluon-String model. The model assumes creation and fragmentation of quark-gluon strings in the interactions. Cross sections of various processes of the creation are determined by an analysis of experimental data on antiproton-proton interactions. Geant4 LUND fragmentation model is used for the simulation of the string fragmentations. As a result, a good description of a wide set of experimental data is reached.A generalization of the approach for antiproton-nucleus and antinucleus-nucleus interactions requires a knowledge of total and inelastic cross sections of these processes. The cross sections are calculated in the Glauber approximation. Good results are obtained for all experimentally known cross sections.Usually, the asymptotic Abramovsky-Gribov-Kancheli (AGK) cutting rules are applied for a determination of the multiplicity of produced strings. We propose finite energy corrections to the AGK rules for an extension of the model to low energy domain. Using the cutting rules and the corrections, we describe antiproton-nucleus interactions starting from low energies (E > 50 MeV) up to 1000 GeV. We also reproduce known experimental data on antideuteron interactions with nuclei.So, we have created a unified model of antiproton-proton, antiproton-nucleus and light antinucleus-nucleus interactions. The model reproduces general properties of the interactions. The model is implemented in the FTF model of Geant4 toolkit and can be accessed using the FTF_BERT PhysicsList.

“…The Gaussian form from [152,154] was used for the amplitude and for the nuclear density the Woods-Saxon distribution for intermediate and heavy nuclei and the Gaussian form for light nuclei was used, with parameters from the paper [157]. Details of the calculations are presented in [158].…”

During the last two to three years extensive development of the Geant4 simulation toolkit has occurred, which will culminate in a major release at the end of 2013. This development includes the adoption of multi-threading, the extension and improvement of physics models, improvements to the geometry modeler with a revised implementation of most geometrical primitives, advances in visualization and graphical user interfaces (GUI), the move from GNU make to CMake and the extension and automation of the Geant4 testing suite. The reasons for and implementation of multi-threading will be discussed. Certain electromagnetic and hadronic model extensions will also be discussed along with their effects on calorimeter results. Finally, visualization and GUI improvements will be highlighted along with the new configuration, build and testing systems.
