Without a physics list, Geant4 won't do anything. G4 comes with a number of pre-constructed lists, and for now I plan to use "QGSP_BERT". It has the following properties:

• Standard EM physics processes.
• Quark-gluon string model for high energies (> 20GeV)
• Low Energy Parameterized (LEP) for medium energies (10<E<20GeV)
• Gertini-style cascade for low energies (< 10GeV)
• LEP, HEP for all anti-baryons (LEP,HEP = low/high energy parameterized, from GHEISHA)
• Gamma-nuclear model added for E<3.5 GeV (comments from "Guided Tour of Geant4 Physics List II", talk given at JPL by Dennis Wright)

IMPORTANT: For now, I'm just copying this physics list from the work I did for NuSOnG, which in turn I copied from ATLAS. More thought is needed for the physics list for MicroBooNE.

If you decide to replace QGSP_BERT with another of G4's pre-supplied physics lists, you can just do a global replace on that name in this header; nothing else need change (except the comments, of course!).

Things become more complex when you're using parallel geometries. The physics processes have to be duplicated in the parallel world. There's a G4 facility for doing this, but it's not part of the pre-supplied physics lists.

Hence this class. It takes the physics from QGSP_BERT, but it extends one of the methods to include recognition of physics processes in the parallel world.
