Hi,

when running my simulation macro (revision 19539) i get the following error when using Geant4:

TG4PrimaryGeneratorAction::TransformPrimaries:
G4ParticleTable::FindParticle() failed for XXX pdgEncoding=88888.
*** TG4Exception: Aborting execution ***

seems like the pbarpSystem is not defined.

With Geant3 everything is working properly.

Best regards and thanks a lot

Andreas

Which input are you using for the simulation?

I am using this decay File:

noPhotos
Decay pbarpSystem
1.0 psi(3770) PHSP;
Enddecay

Decay psi(3770)
1.0 D0 anti-D0 PHSP;
Enddecay

Decay anti-D0
1.0 K+ pi- PHSP;
Enddecay

Decay D0
1.0 K_S0 pi+ pi- PHSP;
Enddecay

End

On my machine the error is reproducable with this decay file using the sim_complete.C in macro/run and the PndEvtGenDirect at the Psi(3770) mass.

In your sim_complete EvtGen->SetStoreTree(XXX) is kTRUE or kFALSE?

Do you have the same problem with kFALSE?

With SetStoreTree set to kFALSE its running properly.

Hi,


the following part of your decay file looks strange for me:


Decay pbarpSystem
1.0 psi(3770) PHSP;
Enddecay


Could you try again running the simulation with psi(2S) as initial resonance instead of pbarpSystem?


Cheers,
Klaus

Hi,

i changed the decay file to

noPhotos

Decay psi(3770)
1.0 D0 anti-D0 PHSP;
Enddecay

Decay anti-D0
1.0 K+ pi- PHSP;
Enddecay

Decay D0
1.0 K_S0 pi+ pi- PHSP;
Enddecay

End

now the error is(its still only crashing with TGeant4):

TG4PrimaryGeneratorAction::TransformPrimaries:
G4ParticleTable::FindParticle() failed for XXX pdgEncoding=40443.
*** TG4Exception: Aborting execution ***

40443 is the pdg code of the psi(3770).

best regards

Andreas

Hi,

EvtGen has its own description of particles in the EvtGen/evt.pdl file. This mostly matches the root particle description (most probably used in Geant4) defined in fairsoft/etc/pdg_table.txt.
The Psi(2S) for example has the pdgcode and name (30443,"psi(2S)) in EvtGen and (100443,"psi'") in root. Same holds for the psi(3770). The pbarpsystem is even not defined in root.

Geant3 is not so picky about the particle tree, as it tess you the error/warning "can be safely ignored". These particles are not tracked - so why bothering.

To put a particle definition to the TDatabasePDG you may use:
TDatabasePDG::Instance()->AddParticle(...)
Just put it to the macro before FairRun::Run() and your initila system (also pbarp if you like) will be present.

I have the converter from Rho ready in the banks.

However, I think adjusting EvtGen to use the root pdg table would be advisable: one list only.

Cheers.
Ralf

Still I do not understand why Geant4 is processing particles which should not be processed, and whoch are not processed by Geant3 as it should be. Maybe there are some problems in the SetStoreTree implementation in the PndEvtGenDirect?

This problem should be fixednow, thanks to Mohammad, you can run geant4 w/o crashes.
If you see something strange please report.
