-Most of the pre-packaged physics lists use "standard" electromagnetic physics processes. The "standard" EM processes are defined with classes: G4EmStandardPhysics, G4EmStandardPhysics_option1, G4EmStandardPhysics_option2 and G4EmStandardPhysics_option3. If you want to use "low energy" electromagnetic physics processes (defined with classes G4EmLivermorePhysics, G4EmLivermorePolarizedPhysics, G4EmPenelopePhysics and G4EmDNAPhysics) in the pre-packaged physics list you have to define them in your physics list class (see example ProtonPencilBeam).
 For example, if you want to simulate clinical proton beam of energy 150 MeV you can use pre-packaged physics list e.g. QGSP_BIC, QGSP_BERT and FTFP_BERT. If you are interested in Bragg curve physics, use a physics list ending in "EMV" or "EMX" e.g. QGSP_BERT_EMV.
