When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.16150, author = "{CMS Collaboration}", title = "{Measurement of the relative prompt production rate of chi(c2) and chi(c1) in pp collisions at sqrt(s) = 7 TeV}", howpublished = "{HEPData (collection)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.16150}" }

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

@misc{hepdata.16150.v1, author = "{CMS Collaboration}", title = "{Measurement of the relative prompt production rate of chi(c2) and chi(c1) in pp collisions at sqrt(s) = 7 TeV (Version 1)}", howpublished = "{HEPData (collection)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.16150.v1}" }

You can also cite this table directly.

@misc{hepdata.16150.v1/t3, author = "{CMS Collaboration}", title = "{``Table 3'' of ``Measurement of the relative prompt production rate of chi(c2) and chi(c1) in pp collisions at sqrt(s) = 7 TeV'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.16150.v1/t3}" }
