When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.81936, author = "{CMS Collaboration}", title = "{Measurement of vector boson scattering and constraints on anomalous quartic couplings from events with four leptons and two jets in proton-proton collisions at sqrt(s) = 13 TeV}", howpublished = "{HEPData (collection)}", year = 2018, note = "\url{https://doi.org/10.17182/hepdata.81936}" }

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

@misc{hepdata.81936.v1, author = "{CMS Collaboration}", title = "{Measurement of vector boson scattering and constraints on anomalous quartic couplings from events with four leptons and two jets in proton-proton collisions at sqrt(s) = 13 TeV (Version 1)}", howpublished = "{HEPData (collection)}", year = 2018, note = "\url{https://doi.org/10.17182/hepdata.81936.v1}" }

You can also cite this table directly.

@misc{hepdata.81936.v1/t1, author = "{CMS Collaboration}", title = "{``Table 1'' of ``Measurement of vector boson scattering and constraints on anomalous quartic couplings from events with four leptons and two jets in proton-proton collisions at sqrt(s) = 13 TeV'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2018, note = "\url{https://doi.org/10.17182/hepdata.81936.v1/t1}" }
