When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.64158, author = "{LHCf Collaboration}", title = "{Transverse momentum distribution and nuclear modification factor of forward neutral pion in proton--lead collisions at $\sqrt{s_{NN}} = 5.02$TeV}", howpublished = "{HEPData (collection)}", year = 2014, note = "\url{https://doi.org/10.17182/hepdata.64158}" }

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

@misc{hepdata.64158.v1, author = "{LHCf Collaboration}", title = "{Transverse momentum distribution and nuclear modification factor of forward neutral pion in proton--lead collisions at $\sqrt{s_{NN}} = 5.02$TeV (Version 1)}", howpublished = "{HEPData (collection)}", year = 2014, note = "\url{https://doi.org/10.17182/hepdata.64158.v1}" }

You can also cite this table directly.
