When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.68389, author = "{ATLAS Collaboration}", title = "{Search for production of $WW/WZ$ resonances decaying to a lepton, neutrino and jets in $pp$ collisions at $\sqrt{s}$ = 8 TeV with the ATLAS detector}", howpublished = "{HEPData (collection)}", year = 2015, note = "\url{https://doi.org/10.17182/hepdata.68389}" }

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

@misc{hepdata.68389.v1, author = "{ATLAS Collaboration}", title = "{Search for production of $WW/WZ$ resonances decaying to a lepton, neutrino and jets in $pp$ collisions at $\sqrt{s}$ = 8 TeV with the ATLAS detector (Version 1)}", howpublished = "{HEPData (collection)}", year = 2015, note = "\url{https://doi.org/10.17182/hepdata.68389.v1}" }

You can also cite this table directly.

@misc{hepdata.68389.v1/t5, author = "{ATLAS Collaboration}", title = "{``Table 5'' of ``Search for production of $WW/WZ$ resonances decaying to a lepton, neutrino and jets in $pp$ collisions at $\sqrt{s}$ = 8 TeV with the ATLAS detector'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2015, note = "\url{https://doi.org/10.17182/hepdata.68389.v1/t5}" }
