I'm simulating the channel
J/psi pi0 pi0 at the energy in the center of mass of the X(3872).
I select j/psi->e+e- in this way:
TString pidalg = "PidChargedProbability";
theAnalysis->FillList(eminus, "ElectronLooseMinus", pidalg);
theAnalysis->FillList(eplus, "ElectronTightPlus", pidalg);
in this way only 20% of J/psi are reconstructed.
If I did not (theAnalysis->McTruthMatch(jpsiee[j]))
I have 66% of J/psi reconstructed.
Maybe something is going wrong with the McTruthMatch?
Do you have an idea?
Thanks a lot
