The W boson mass analysis from the ATLAS Open Data release of 2020, with RDataFrame.

This tutorial is the analysis of the W boson mass taken from the ATLAS Open Data release in 2020 (http://opendata.atlas.cern/release/2020/documentation/). The data was recorded with the ATLAS detector during 2016 at a center-of-mass energy of 13 TeV. W bosons are produced frequently at the LHC and are an important background to studies of Standard Model processes, for example the Higgs boson analyses.

The analysis is translated to a RDataFrame workflow processing up to 60 GB of simulated events and data. By default the analysis runs on a preskimmed dataset to reduce the runtime. The full dataset can be used with the –full-dataset argument and you can also run only on a fraction of the original dataset using the argument –lumi-scale.
