To allow comparison to results obtained with older releases of Geant4, i.e. 8.2 and before, these lists are provided for a transisition period. QGSP_INCLXX This is an experimental physics list that uses the Liege Intranuclear Cascade model (INCL++) for proton-, neutron- and pion-induced reactions below ~3 GeV, instead of BERT or BIC.

Using INCL++ in Geant4. The INCL++ model is distributed with the Geant4 toolkit for particle transport since v9.5. We always recommend to use the latest version of Geant4, which can be downloaded from the Geant4 web site.See also the page about INCL++ in the Geant4 process/model catalog.. There are dedicated (experimental) physics lists that use INCL++ in the intermediate-energy range.

This value can be specified in the optional SetCuts() method of your Physics list or via UI command, for eg. to set a range cut of 10 micrometers, one can use: /run/setCut 0.01 mm or for a given particle type (for e.g. electron) A new Geant4 physics list is prepared for nuclear physics applications in the domain dominated by spallation. The C++ translation of original Fortran INCL intra-nuclear cascade and ABLA fission/de-excitation codes are used in the physics list. The INCL model prepared is well established for targets heavier than Aluminium and projectile energies from 150 MeV up to 2.5 GeV - 3 GeV. Validity of This physics list uses the Geant4 standard electromagnetic physics processes. Where hadronic processes are used the model assigned to the process is cited. Boson Physics .

Geant4 19.05.05 PhysicsList 25 LHC Physics From TeV down to MeV energy scale for precise simulation of detector response Following lists are recommended for Geant4 version 7.0p01: – QGSP_GN (Quark Gluon String + PreCompound + Gamma-Nuclear) – QGSP_BERT (Quark Gluon String + PreCompound + Bertini Cascade) – QGSC (Quark Gluon String + CHIPS) The hadron physics constructor defines all stable and long-lived baryons, and all long-lived mesons. These are the particles that Geant4 can track and therefore require processes to be assigned. Short-lived particles are not tracked, but they appear in some hadronic models, so a large list of resonances, quarks and diquarks is also defined.

Physics lists include those originally named 'educated guess physics lists'.

Further investigations are needed for the case of heavier materials. Updating/augmenting Physics Lists (3) Steps taken so far: –radioactive decay added to local 9.4 version of Shielding physics list (Mike Kelsey) –9.4 version of Shielding (w/o radioactive decay) back-ported to local copy of Geant4 9.3p02 •temporary measure until users are satisfied with 9.4 and until next official version of Geant4 comes out Physics lists 17 !

Various Physics Lists are possible and useful, according to the specific application domains (e.g.

CT scan data and small tissue volume analysis with Geant4 code system timber construction systems in terms of design and structure physics solutions.

However, in the case users need to combine Geant4-DNA processes with other Geant4 electromagnetic processes (e.g. other electron processes Physics’I:’Physics’Lists’ Geant4’Tutorial’atStanford’ 4’March’2014’ Dennis’Wright(SLAC)’ Geant4’10.0’p01’ Several Geant4 low-energy studies have utilized the Standard Electromagnetic (EM) Physics List (PL) option 4, as this physics list provides the most detailed implementation of electromagnetic processes for low energy photons and it was suggested by the AAPM TG-195 . Other options in the Standard Electromagnetic Physics List series are meant for fast simulation or high energy applications.
