Now, for episode 3 of 
Today, we'll be using the MadAnalysis5 software package to simulate detectors at the LHC. We ingest our simulated pp collisions, generated in episode 2, through a simulated detector (ATLAS).
Here's the steps I took to complete the task:
$ cd ~/physics # Task 1
$ git clone https://github.com/MadAnalysis/madanalysis5
$ cd madanalysis5
$ pip install matplotlib # Task 2
$ pip install scipy
$ sudo apt-get install texlive
$ sudo apt-get install texlive-latex-extra # Alleviates errors generating PDF/DVI files.
$ ./bin/ma5
ma5>install fastjet
ma5>exit
$ # Task 3
$ ./bin/ma5 -R madanalysis/input/ATLAS_default.ma5
ma5>import ~/physics/MG5_aMC_v2_9_9/pp_tt/Events/run_01_decayed_1/tag_1_pythia8_events.hepmc
ma5>set main.outputfile = atlas_pp_tt.lhe.gz
ma5>submit
ma5>exit
$ ./bin/ma5 # Task 4
ma5>import ANALYSIS_0/Output/SAF/_defaultset/lheEvents0_0/atlas_pp_tt.lhe.gz as ttbar
ma5>set ttbar.xsection = 505.8
ma5>plot NAPID
ma5>submit
That's roughly it. I checked both the output MadAnalysis5 PDF files and images and here's the resulting histogram of particle counts:
It has roughly the same distribution as
This has been a short update and I'm looking forward to diving more into the physics in episode 4. All in all, it took me just a few hours to run the steps above and write the post.
See all of yall around!
