Theoretical Branching Ratio

Hi Everyone,

I’m a newbie to the forum and I have the following question: Where do I find the theoretical branching ratio for the decay of the muon in the GEANT4 software? I have searched and found calls to the function GetBR and SetBR, but I haven’t been able to locate where the values are actually calculated or defined.

For particles like the muon, the decay table is associated with the particle definition itself. In particles/leptons/src/ you’ll find a reference to G4MuonDecayChannel, which is implemented in particles/management/src/ In the same directory, you’ll find, which has more complex code.

Thanks, Michael! That info is what I was looking for! I appreciate it!
