OK, sorry, but I don't quite get it yet.

To be more specifically - I think QGSP_BERT_EMZ is a good starting point for my application 
(18GeV e- beam on a copper-water dump), but I am interested in muon production, so I need at 
least the following additional processes activated:

- G4GammaConversionToMuons (for gamma)
- G4eeToHadrons (for e+)
- G4AnnihiToMuPair (for e+)

I understand that I can add additional Physics via RegisterPhysics(), e.g. G4EmExtraPhysics() or 
G4RadioactiveDecayPhysics(). My idea would be to create a custom Physics class containing the three 
processes, and call it e.g. G4EmExtraMuonPhysics(). Is it possible to register this custom class to the reference physics list, or do I indeed (as in 
solution 1) ) have to modify an existing Physics module/builder/constructor (I am a little bit lost in which 
is called which)?

For what concerns Solution 2) I do not fully understand what you mean, even looking at example $G4INSTALL/examples/extended/hadronic/Hadr02.

Cheers,

Stefan
