Simplified Run 2 Analysis: Glossary

Key Points

Jupyter & Coffea setup (Jan 4)
  • Get ready for the lesson as a whole

Analysis introduction
  • Understanding the basic physics will help you understand how to translate physics into computer code.

  • We will be perfoming a real but simplified HEP analysis using CMS Run2 open data using columnar analysis.

Have some Coffea
  • Coffea is a framework which builds upons several tools to make columnar analysis more efficient in HEP.

  • Schemas are a simple way of rearranging our data content so it is easier to manipulate

Bonus Material: build the ttbar analysis
  • Basic selection requirements are implemented very easily using columnar analysis

  • Coffea processors encapsulate an analysis so it becomes deployment-neutral

Bonus Material: Systematics and Statistics
  • Systematic variations are conveniently handled with Coffea

  • We construct statistical models to estimate systematics in our analysis.

  • cabinetry and pyhf are the tools we use here.
