[Rivet] Exclude the charged leptons from the charged particle selection

[Shayma Wahdan]

Dear Rivet community,

I am trying to exclude the charged leptons from the charged particle selection
what I do exactly:

in the int part I add:

      ChargedFinalState cfs(-2.5, 2.5, 1.0*GeV);
      addProjection(cfs, "CFS");

    // to exclude the charged leptons

     VetoedFinalState vfs(cfs);
      vfs.addVetoPairId(PID::ELECTRON);
      vfs.addVetoPairId(PID::MUON);
      vfs.addVetoPairId(PID::TAU);
      addProjection(vfs,"VFS");


 and in the analyze

     const ChargedFinalState& ChargedParticleCollection = applyProjection<VetoedFinalState>(event, "VFS");

The compliling goes well, while in the running almost none of the events get selected.

Any suggestions please??

Note: I got the idea from this Rivet analysis page http://rivet.hepforge.org/code/2.2.1/a00496_source.html

Best Regards,
Shayma'
