  • Use the macro V10_terceiromais_dark_Higgs.C to check the m_{J} variable;
  • Find the best value of the Punzi significance for the m_{J}^{C} and m_{J}^{W} using the macro punzi_eff_bg_separated.C;
  • Get the number of events of signal and BG in that region, and the efficiency using the macro punzi_eff_table_cutflow.C;

  • Convert everything to xsec using the expression \sigma = N/(lumin x eff), and multiplying the efficiency by 1.2 * xsec (with MET cut)/xsec (without MET cut).

  I've found the 1.2 factor inside the MadGraph folder, and it's just a grep "1.2" *.f inside Template/LO/Source to see it. This factor doesn't appear in the NLO processes.

I've already simulated the 156 GeV m_{d_{H}} without MET cut to calculate the cross section, and the result was 0.05776 pb. Today I'll also do the same thing with the Z' masses.

The process with the MET cut have a cross section equal to 0.004846 pb. The file in the Delphes folder is called mais_certo_300k_156gev.root.
