Hi Kristin,

just add the following to your VetoedFinalState (veto) in init():

      veto.addVetoId 
<https://rivet.hepforge.org/code/dev/a00364.html#a2f2f68def4d0728caded8f98bc492ec8>.(PID::MUON);
      veto.addVetoId 
<https://rivet.hepforge.org/code/dev/a00364.html#a2f2f68def4d0728caded8f98bc492ec8>.(PID::ELECTRON);

Cheers,
Holger
