Scope of the tutorial

Last update: 14 Nov 2022 [History] [Edit]

This is a new format for the analysis software tutorial as of autumn 2022. It is largely inspired by and uses much of the same material as the previous tutorial. The main difference is that this tutorial is designed around following an example physics analysis through the most common steps with centrally provided tools.

The tutorial follows the Run 2 dilepton leptoquark analysis. It is not meant to be a perfect reproduction of the result, but instead is meant to give you an idea of how to do the various steps in the analysis workflow. The steps included in this analysis are:

  • MC sample production
  • Producing ntuples from DAOD_PHYS files
  • Accessing and using physics objects
  • Running jobs on batch systems and the grid
  • Plotting kinematic variables
  • Optimizing analysis selection cuts
  • Implementing systematic uncertainties
  • Using Boosted Decision Trees
  • Statistical analysis and setting limits

Many of the steps in the analysis workflow are simplified for the sake of time. For example, you will be asked to produce a single file for analysis and the full set of files will be provided. Similarly, you will be guided on a quick analysis optimization to show you some techniques, but in practice this will be a much more involved process.
