The C++ translation of original Fortran INCL intra-nuclear cascade and ABLA fission/de-excitation codes are used in the physics list. use reference Physics lists provided with Geant4 (QBBC, ….) ! build his/her own Physics list in his/her application ! or use already available EM physics constructors 1. If you choose to build your own Low Energy EM Physics list ! Refer to the Geant4 Low Energy EM working group website, Modular Physics Lists. The default list we provide is a Modular physics list.

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.

Other options in the Standard Electromagnetic Physics List series are meant for fast simulation or high energy applications. yes.

Point (1) - (4) corresponds to a pre-initialization of Geant4, after point (5) no more changes to the geometry or the physics list can be made as the initialization

Refer to the Geant4 Low Energy EM working group website, Physics Lists provided Geant4 created a set of physics lists for typical use cases in a range of applications areas, see below. These lists are maintained, and in general evolve with new releases of Geant4 to include new options for processes, or to adapt to new validation. Particle Physics Medical Physics Space Physics Physics list support consists of development of prototype physics lists, testing based on simple examples, updating the lists as new Geant4 releases become available and validation against experimental data. Available Physics Lists Current physics lists include those developed to support experiments based at least in part at SLAC. 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) 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. see Geant4 web page under User Support, item 10b !

QGSP_BERT_HP which uses the Bertini intranuclear cascade model to describe the inelastic interactions of protons and neutrons, QGSP_BIC_HP which uses n A physics list for a realistic detector can become cumbersome n Geant4 supplies many physics processes which the user must assign to the particles n Processes and geometry determine where and how a particle interacts n The precision of particle stopping and the production of secondary particles are determined by a cut in range The physics list contains standard electromagnetic processes and the radioactiveDecay module for GenericIon. It is defined in the B3PhysicsList class as a Geant4 modular physics list with registered Geant4 physics builders: Geant4 is a Monte Carlo code extensively used in medical physics for a wide range of applications, such as dosimetry, micro‐ and nanodosimetry, 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. 2020-06-01 Physics List is a set of consistent physics models for each particle in application" • Users need guidance or help" • Geant4 offers starting points" • Responsibility of application developer" – To choose and, if needed, further develop" – To validate for his use case" • For EM physics… Geant4 Materials Tutorial Daniel Brandt, 04 April 2012 The physics list The physics list inherits from G4VUserPhysicsList. The easiest way to implement this is to use a Geant4 standard physics list G4VUserPhysicsList* physics = new FTFP_BERT(); runManager->SetUserInitialization(physics); Alternatively you could write your own. It must implement Geant4 at Fermilab Geant4 is a toolkit for the modeling of the passage of particles through matter. Its application areas include high energy physics and nuclear experiments, medical, accelerator and space physics.
