The problem at NLO was solved using the newest version of MadGraph (2.6.5), with some changes in the files CT_interface.f. When an process is generated, at the output folder there is the following path /MG5_aMC_v2_6_5/output_folder/SubProcesses/P0_something_something/V0_something_something/CT_interface.f. Inside those files, approximately at the line 650 (can be higher or lower), two quantities that must be changed are (it's just an extra zero that must be erased) ABSP_TMP(I)=0.E0+0_16 and P_TMP(I,J)=0.E0+0_16. The zero after the letter E must be erased!! Otherwise, the check_poles test will fail.



I've been talking to Thiago to rewrite the macro, and apparently it's good now, but I'm having problems when applying it to the signal (lots of fat jets have only one jet inside it). The problem seems to be that I forgot to change the ParameterR variable inside the Delphes card when generating the 300000 events for each mass of the dark Higgs. I've simulated 30000 events of the dark Higgs signal processes for m_{d_{H}} = 50 GeV to check it. EVERY IMAGE ABOUT THE DARK HIGGS IN THIS TWIKI IS WRONG!!!

The name of the folder is dh_50gev_30000_paperjetreco, and I'm using the macro (inside Delphes folder) V3_terceiromais_dark_Higgs.C. I'll also change the way the jets are generated: for now, the jets are reconstructed only using the charged particles (tracks); I'll use the particle flow that includes everything (in Delphes it's the EFlow array).

In the mean time, Thiago taught me how to write a .root file that contains all the canvases I need, instead of running the macro over and over again (extremely helpful). I also learned how to properly handle data structures in C++, and that save so much time and effort. It makes everything more clear.
