Hi all,

i have again the problem that McTruthMatch always returns false, but at another level.

Now I try to match the whole decaytree of my Lambda LambdaBar decay.

What I do:

RhoCandList ppbarsystem;

ppbarsystem.Combine(lambda, lambdabar);
ppbarsystem.SetType(88888);

for(int b=0;b<ppbarsystem.GetLength();b++)
{

    if(theAnalysis->McTruthMatch(ppbarsystem[b],2,true))
		{
		// fill some histogram
		}
}



Output created:

Info in <PndMcTruthMatch::MctMatch>: Investigating in particle with pdg: 88888 and 2 daughters
Info in <PndMcTruthMatch::MctMatch>: Investigating in particle with pdg: 3122 and 2 daughters

Info in <PndMcTruthMatch::MctMatch>: rejected by not existing MC truth of daughter zero


This appears for all my llbar combinations.
Seems that the MCTruth tree is not build. Should this work and something is going wrong, or am I doing something wrong?

Best regards

Simone

Hi Simone,


I observe very similar problems. I believe this it due to a mismatch of the PDG codes used by EvtGen and those in TDatabasePDG.

Could you try to run with

  theAnalysis->SetVerbose(1);


I get some errors like

-W- CreateMcCandidate: strange PDG code:30443


Should be in your case 88888. Can you confirm this?


Best,
Klaus

Hello Klaus,

yes, I can confirm this. Would it help to insert the PDG code before in the files?

In addition I have a new problem.
In the next line my analysis task crashes with the following output :

This is not correlated with the verbose level, I had this before. I cant see a correlation with my code. Sometimes the codes runs without a crash, sometimes not Sad

Hi,


this apparently is a bug I just spotted in PndAnalysis. I'll try to fix it in trunk.

You can try as a workaround to use the method 'McTruthMatch(RhoCandidate)' instead 'McTruthMatch(RhoCandList)' for the time being.


Best,
Klaus

Why PndAnalysis::fVerbose is static?

[sorry, wrong topic]

Hello Klaus,

I didnt recognise that I used McTruthMatch(RhoCandList), with McTruthMatch(RhoCandList) it works.

Hello Stefano,

The static definition of fVerbose makes some problem for my code. Maybe you have similar problems.
I opend a new topix due to this in the Bugs forum
( https://forum.gsi.de/index.php?t=tree&th=3938&start=0&rid=15 62&S=ab06a719b66b530ae5b7a8f7a9f6cdd3)

Hi,


if you update trunk/PndTools/AnalysisTools, you get the fixed version (which works for me fine).

Why fVerbose is static, I actually either don't understand. Most likely Ralf had some reason to put it like this, but he's in vacations the rest of this week.


Best,
Klaus

The fixed for the McTruthMatch(RhoCandList) function works also fine for me.

Hi Klaus, Hi all

Quote:

I believe this it due to a mismatch of the PDG codes used by EvtGen and those in TDatabasePDG.


Can't I insert somehow the 88888 pdg code in the database manualy so that the match works?

I saw in this post:
https://forum.gsi.de/index.php?t=tree&goto=14689&rid=1562&S= ab06a719b66b530ae5b7a8f7a9f6cdd3&srch=TDatabasePDG#msg_14689
that one can do it, but I dont know what to fill in for some the variables.
virtual TParticlePDG*   AddParticle(const char*  Name,
                                    const char*  Title,
                                    Double_t     Mass,
                                    Bool_t       Stable,
                                    Double_t     DecayWidth,
                                    Double_t     Charge,
                                    const char*  ParticleClass,
                                    Int_t        PdgCode,
                                    Int_t        Anti=-1,
                                    Int_t        TrackingCode=0);


Does someone know?

best regards

Hi Simone,


you could try something like

TDatabasePDG::Instance()->AddParticle("pbarpSystem","pbarpSystem",1.9,kFALSE,0.1,0,"",88888)

I think, for the truth match only the pdg code is important anyways.


Best regards,
Klaus

Maybe it would be good to prepare some class who is doing such initialization for all our strange states (pbarpsystem, pbarpsystem012, pbardsystem...), in order to avoid possible problems (i.e. evtgen with geant4 with SetStoreTree).
Maybe some function is gconfig folder?

Hi all!

I added the line Klaus suggested to the Init() function of my analysis task.
The warning of the strange PDG code is gone, but Match still doesnt work. Sad

Hi Simone,


there is still a (known) bug in the tree match.

I'm going to discuss with Ralf (who is supposed to be back from vacations tomorrow) about a fix for MC match which worked for my psi(2S), but it's some kind of preliminary.

Unfortunately we have a problem with our linux farm at the moment, when it's fixed I can send you the patched source of PndAnalysis.cxx.


Best,
Klaus

Yes, this is supposed to work now. At least it does for the tutorial macros.
