When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.95234, author = "{CMS Collaboration}", title = "{Fragmentation of jets containing a prompt J$/\psi$ meson in PbPb and pp collisions at $\sqrt{s_\mathrm{NN}} =$ 5.02 TeV}", howpublished = "{HEPData (collection)}", year = 2021, note = "\url{https://doi.org/10.17182/hepdata.95234}" }

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

@misc{hepdata.95234.v1, author = "{CMS Collaboration}", title = "{Fragmentation of jets containing a prompt J$/\psi$ meson in PbPb and pp collisions at $\sqrt{s_\mathrm{NN}} =$ 5.02 TeV (Version 1)}", howpublished = "{HEPData (collection)}", year = 2021, note = "\url{https://doi.org/10.17182/hepdata.95234.v1}" }

You can also cite this table directly.
