When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.61319, author = "{ATLAS Collaboration}", title = "{Search for long-lived, multi-charged particles in pp collisions at $\sqrt{s}$=7 TeV using the ATLAS detector}", howpublished = "{HEPData (collection)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.61319}" }

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

@misc{hepdata.61319.v1, author = "{ATLAS Collaboration}", title = "{Search for long-lived, multi-charged particles in pp collisions at $\sqrt{s}$=7 TeV using the ATLAS detector (Version 1)}", howpublished = "{HEPData (collection)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.61319.v1}" }

You can also cite this table directly.

@misc{hepdata.61319.v1/t1, author = "{ATLAS Collaboration}", title = "{``Table 1'' of ``Search for long-lived, multi-charged particles in pp collisions at $\sqrt{s}$=7 TeV using the ATLAS detector'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.61319.v1/t1}" }
