Dear all,

I would like to ask you if there is a way to reconstruct the J/psi in both
the electronic and muonic decay modes.
I set both the decay modes into my decay file and then in my macro I do:
jpsiee.Combine(eminus,eplus);
jpsimm.SetType(443);
for(j=0;j<jpsiee.GetLength();++j){
invmassee->Fill(jpsiee[j]->M());
}

jpsimm.Combine(muminus,muplus);
jpsimm.SetType(443);
for(j=0;j<jpsimm.GetLength();++j){
invmassmm->Fill(jpsimm[j]->M());
}
Now, is there the possibility to have a single RhoCandList where the J/psi
is formed by both jpsiee and jpsimmm?
I would like to have a single RhoCandList
there the J/psi is formed by both the electronic and muonic decay modes.

Thanks in advance,
Elisa
