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
