      Dear Mahmoud,

       

      it is good to see that the code runs now and the plots are filled with data! This is real progress.

       

      However, from the code fragment you send, I think there is still something wrong with the "gen jets", thus, the jet plots you send now are probably all wrong.

       

      The line "jet_particles_list.append(self.fChain.genParticlesp4[itowG])" must, of course, be located INSIDE the itwoG loop -- in the same place where you fill the histograms like "self.hist["eta"].Fill(eta)" etc.

       

      As you do it right now, each jet is just one random particle. This is not correct.

       

      So this is the todo list:

       

      1/ fix the code as explained above

       

      2/ also add "calo jets" (so far you only plot "gen jets"). The calo jets must be constructed in the same way, but after the loop over the "calo towers p4". I hope this is clear, otherwise send you current code again and we can look at this together.

       

      Cheers,

      Ralf

      Report Hadeel 20m

      This is great progress. Very good! Also the quality of the plots you produced is pretty good and clear. Keep on working like this!

       

      Here are my comments / todo-list:

       

      1/ make each single plot (sub-plot) logarithmic in y-axis: with "gPad->SetLogy(1)"

       

      2/ plot EPOS and pythia  in the SAME figure, using different colors (e.g. EPOS: blue, P8: red).

       

      3/ also plot ZeroBias data on top of the same figure using black markers.

       

      Typically, in such plot you always plot the models as colored lines, and the data with black markers, see e.g. fig 1 of https://arxiv.org/pdf/1812.04095.pdf 

      --> Really try hard to replicate this exact figure style!

       

      Cheers,

      Ralf
