34405468 events. 373 files. 15.5 GiB in total.How were these data generated?
These data were created during LS2 as part of a major reprocessing campaign of the Run 2 data. All data were reprocessed using Athena Release 22, and new corresponding MC simulation samples were produced. These data and MC simulation datasets were processed into ROOT ntuple files from the DAOD_PHYSLITE format that is released as open data for research. For the files in this record, the following skimming selection was applied: At least two jets with at least 20 GeV of pT, at least two leptons passing tight identification requirements with at least 7 GeV of pT, and 30 GeV of missing transverse momentum (i.e. a di-leptonic top-quark enhanced selection)
How can you use these data?
The data and MC simulation provided by the ATLAS experiment in root ntuple format is released under a CC0 license; citation of the data and acknowledgement of the collaboration is requested. This format can be used directly using ROOT or uproot for simple studies and is primarily intended for educational and outreach purposes.
Extensive instructions for interacting with the data, as well as documentation of the dataset naming conventions and their contents, are provided on the ATLAS Open Data website linked below. For those interested in implementing a research-quality data analysis, the open data designed for research (also linked below) may be a better starting point. Please be sure to cite the Open Data that you use, in line with the policy below.
