The Higgs to two photons analysis from the ATLAS Open Data 2020 release, with RDataFrame.
This tutorial is the Higgs to two photons analysis from the ATLAS Open Data release in 2020 (http://opendata.atlas.cern/release/2020/documentation/). The data was taken with the ATLAS detector during 2016 at a center-of-mass energy of 13 TeV. Although the Higgs to two photons decay is very rare, the contribution of the Higgs can be seen as a narrow peak around 125 GeV because of the excellent reconstruction and identification efficiency of photons at the ATLAS experiment.
The analysis is translated to a RDataFrame workflow processing 1.7 GB of simulated events and data.
