 Delphes imposes an efficiency of 0 in reco leptons that have p_T < 10 GeV (great issue concerning the mass difference that I set). Gen leptons have very low/high p_T, and reco ones have p_T > 10 GeV from the cut I described before.

In run_17 I set m_F = 300 GeV and m_{s0} = 125 GeV with c\tau ~ 200 mm to see if the problem with the leptons would continue (I didn't change any generation restriction in Madgraph or Pythia or Delphes).

The number of generated s0 and electrons + muons are equal ~ 11000, but they are much lower than the expected (~ 20000). However, the number of reconstructed electrons + muons is around 15000 which is a great improvement. This was due to the Delphes restriction on leptons p_T indeed.

Run_18 is the same as the above, but with only 100 events. I am going to check the hepmc file to see if there is any valuable information about why some s0 and generated electrons/muons are missing. The hepmc file showed that even though every s0 or lepton that comes out of the F decay appear there as a stable particle (status=1), not all of them have the hardest subprcess outgoing status (23). I am going to talk to Thiago about this.
