When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.60297, author = "{ALICE Collaboration}", title = "{$J/\psi$ suppression at forward rapidity in Pb-Pb collisions at $\sqrt{s_{NN}}=2.76$ TeV}", howpublished = "{HEPData (collection)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.60297}" }

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

@misc{hepdata.60297.v1, author = "{ALICE Collaboration}", title = "{$J/\psi$ suppression at forward rapidity in Pb-Pb collisions at $\sqrt{s_{NN}}=2.76$ TeV (Version 1)}", howpublished = "{HEPData (collection)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.60297.v1}" }

You can also cite this table directly.

@misc{hepdata.60297.v1/t2, author = "{ALICE Collaboration}", title = "{``Table 2'' of ``$J/\psi$ suppression at forward rapidity in Pb-Pb collisions at $\sqrt{s_{NN}}=2.76$ TeV'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.60297.v1/t2}" }
