I had tried something to implement mu -> eee.
I used G4PhaseSpaceDecayChannel in the ConstructProcess in my physics list. The relevant code is given below......
G4ParticleDefinition* muplus = G4MuonMinus::MuonMinusDefinition(); G4DecayTable* muplusTable = muplus->GetDecayTable();
G4VDecayChannel*mode1 = new G4PhaseSpaceDecayChannel("mu+",0.05,3,"e+","e-","e+"); muplusTable->Insert(mode1);
//For mu- G4ParticleDefinition* muminus = G4MuonMinus::MuonMinusDefinition(); G4DecayTable* muminusTable = muminus->GetDecayTable();
G4VDecayChannel* mode2 = new G4PhaseSpaceDecayChannel("mu-",0.5,3,"e+","e-","e-"); muminusTable->Insert(mode2);
Then using the vis commands I set the branching ratio of the normal muon decay to zero and that of mu -> eee to 1.
This gives and out put
G4DecayTable: mu- 0: BR: 1 [Muon Decay] : e- anti_nu_e nu_mu 1: BR: 1 [Phase Space] : e+ e- e-
Everything seems to be in place.. but still i dont get the phase space decay in my simulation.. instead Geant gives the normal muon decay whose branching ratio I have set to 0..
I am stuck.. Please help..
