When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.61728, author = "{D0 Collaboration}", title = "{Measurement of the ratio of three-jet to two-jet cross sections in pp-bar collisions at sqrt(s) = 1.96 TeV}", howpublished = "{HEPData (collection)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.61728}" }

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

@misc{hepdata.61728.v1, author = "{D0 Collaboration}", title = "{Measurement of the ratio of three-jet to two-jet cross sections in pp-bar collisions at sqrt(s) = 1.96 TeV (Version 1)}", howpublished = "{HEPData (collection)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.61728.v1}" }

You can also cite this table directly.

@misc{hepdata.61728.v1/t2, author = "{D0 Collaboration}", title = "{``Table 2'' of ``Measurement of the ratio of three-jet to two-jet cross sections in pp-bar collisions at sqrt(s) = 1.96 TeV'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.61728.v1/t2}" }
