Simulated the signal using the CMS card filtered, with the b-tagging eff changed, and with the object to reconstruct the jets also changed. The name of the folder inside the MG folder is
DM_signal_withelecmuon_change_recojet. The ROOT files inside the Delphes folder are named
DM_signal_withelecmuon_change_recojet50.root,
DM_signal_withelecmuon_change_recojet70.root,
DM_signal_withelecmuon_change_recojet90.root. The macros
plot_varios_fjetmass.C and
maisum_dark_Higgs.C were used in those files. The pdf file
fatjet_mass_CMSrecojet.pdf was created.
- The signal was simulated using 25000 events for each mass of the dark Higgs, with the following luminosities (fb^-1):
- m_{hs} = 50 geV - 34,36;
- m_{hs} = 70 geV - 42,20;
- m_{hs} = 90 geV - 51,21.
Changed the
delphes_card.dat to produce the gen fat jets. Started simulating the signal with it to see what happens with the b-tagging. The name of the folder inside the MG folder is
DM_signal_withelecmuon_genfatjet. The ROOT files inside the Delphes folder are named
DM_signal_withelecmuon_genfatjet50,
DM_signal_withelecmuon_genfatjet70,
DM_signal_withelecmuon_genfatjet90. The macros
plot_varios_fjetmass.C and
maisum_dark_Higgs.C were used in those files. The pdf file
fatjet_mass_CMSgenfatjet.pdf was created.
I'll create another macro to analyze the generated fat jets, just like the reconstructed ones to see the differences.
- The signal was simulated using 25000 events for each mass of the dark Higgs, with the following luminosities (fb^-1):
- m_{hs} = 50 geV - 34,36;
- m_{hs} = 70 geV - 42,20;
- m_{hs} = 90 geV - 51,21.
The next step will be to make the b-tagging by hand, that is, try to match the generated b quarks to the jets (gen and reco), and apply the paper eff to it. Also, the test about the random number could be done with one of the masses to check its role in the fat jet invariant mass histograms.
The slides from 25/02/2019 that I showed to Thiago must be changed to be well understood.

Got a graph exactly like the one in "Hunting the dark Higgs" paper. The name of the file is
ALL_backgrounds_mJ.pdf. Also, the macro used to do it is
ALL_backgrounds_combined_rightratio.C with the files
withelecmuon_ for the backgrounds. I've rescaled the luminosities to 3.2 fb^{-1}, and used a primitive k-factor to do it (choosed 4 because it's the proportion to the ATLAS results). There are some discrepancies between my graph and the paper one that I must talk to Thiago. But it's something.

I've got the right lepton veto using the reconstructed leptons instead of the generated leptons (I guess I was getting ALL of the generated leptons, instead of only the isolated ones). Less then 1% of the signal events were cut using this veto. My problem is still in the b-tagging and the MET cut. The number of events reduced by the MET cut was expected since I'm getting only the end of the tail events (I'll understand this sentence every time). The b-tagging is excluding almost 100% of the signal events, and that is disturbing. To solve it, I've generated some new signal events TREES from Delphes for the 3 dark Higgs masses (10000 events each), which contain the gen particle, the MET, the jet, gen jet, fat jet, gen fat jet, reco electrons and muons branches to do the b-tagging by hand and check what is happening. The folder is named
DM_signal_withelecmuon_btagging_test, and the files are
DM_signal_withelecmuon_btagging_test50,
DM_signal_withelecmuon_btagging_test70,
DM_signal_withelecmuon_btagging_test90. The macro
genfatjet_macro.C was used in those files.
Tried to solve the NLO problem on
MadGraph, but my knowledge doesn't allow me to do it. Must also talk to Thiago about it. I've even tried to use what CLASHEP taught me, but it didn't worked because there is something else missing.
