Citizen Science Entry 3
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 @lemouth described in episode 3.
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!
