When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.15557, author = "{TASSO Collaboration}", title = "{Measurement of the Two Photon Reaction $\gamma \gamma \to \pi^+ \pi^- \pi^+ \pi^-$ at Large Values of $Q^2$}", howpublished = "{HEPData (collection)}", year = 1994, note = "\url{https://doi.org/10.17182/hepdata.15557}" }

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

@misc{hepdata.15557.v1, author = "{TASSO Collaboration}", title = "{Measurement of the Two Photon Reaction $\gamma \gamma \to \pi^+ \pi^- \pi^+ \pi^-$ at Large Values of $Q^2$ (Version 1)}", howpublished = "{HEPData (collection)}", year = 1994, note = "\url{https://doi.org/10.17182/hepdata.15557.v1}" }

You can also cite this table directly.

@misc{hepdata.15557.v1/t1, author = "{TASSO Collaboration}", title = "{``Table 1'' of ``Measurement of the Two Photon Reaction $\gamma \gamma \to \pi^+ \pi^- \pi^+ \pi^-$ at Large Values of $Q^2$'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 1994, note = "\url{https://doi.org/10.17182/hepdata.15557.v1/t1}" }
