When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.92006, author = "{ATLAS Collaboration}", title = "{Search for direct stau production in events with two hadronic $\tau$-leptons in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector}", howpublished = "{HEPData (collection)}", year = 2020, note = "\url{https://doi.org/10.17182/hepdata.92006}" }

or, if you prefer, a specific version of the record:

@misc{hepdata.92006.v2, author = "{ATLAS Collaboration}", title = "{Search for direct stau production in events with two hadronic $\tau$-leptons in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector (Version 2)}", howpublished = "{HEPData (collection)}", year = 2020, note = "\url{https://doi.org/10.17182/hepdata.92006.v2}" }

You can also cite this resource directly.
