When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.58980, author = "{CMS Collaboration}", title = "{Study of high-pT charged particle suppression in PbPb compared to pp collisions at sqrt(sNN)=2.76 TeV}", howpublished = "{HEPData (collection)}", year = 2012, note = "\url{https://doi.org/10.17182/hepdata.58980}" }

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

@misc{hepdata.58980.v1, author = "{CMS Collaboration}", title = "{Study of high-pT charged particle suppression in PbPb compared to pp collisions at sqrt(sNN)=2.76 TeV (Version 1)}", howpublished = "{HEPData (collection)}", year = 2012, note = "\url{https://doi.org/10.17182/hepdata.58980.v1}" }

You can also cite this table directly.

@misc{hepdata.58980.v1/t7, author = "{CMS Collaboration}", title = "{``Table 7'' of ``Study of high-pT charged particle suppression in PbPb compared to pp collisions at sqrt(sNN)=2.76 TeV'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2012, note = "\url{https://doi.org/10.17182/hepdata.58980.v1/t7}" }
