When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.77267, author = "{ATLAS Collaboration}", title = "{Measurement of the cross-section for electroweak production of dijets in association with a $Z$ boson in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector}", howpublished = "{HEPData (collection)}", year = 2018, note = "\url{https://doi.org/10.17182/hepdata.77267}" }

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

@misc{hepdata.77267.v1, author = "{ATLAS Collaboration}", title = "{Measurement of the cross-section for electroweak production of dijets in association with a $Z$ boson in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector (Version 1)}", howpublished = "{HEPData (collection)}", year = 2018, note = "\url{https://doi.org/10.17182/hepdata.77267.v1}" }

You can also cite this table directly.

@misc{hepdata.77267.v1/t1, author = "{ATLAS Collaboration}", title = "{``Table 1'' of ``Measurement of the cross-section for electroweak production of dijets in association with a $Z$ boson in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2018, note = "\url{https://doi.org/10.17182/hepdata.77267.v1/t1}" }
