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.
