When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.77273, author = "{ATLAS Collaboration}", title = "{Search for a new heavy gauge boson resonance decaying into a lepton and missing transverse momentum in 36 fb$^{-1}$ of $pp$ collisions at $\sqrt{s} =$ 13 TeV with the ATLAS experiment}", howpublished = "{HEPData (collection)}", year = 2017, note = "\url{https://doi.org/10.17182/hepdata.77273}" }

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

@misc{hepdata.77273.v1, author = "{ATLAS Collaboration}", title = "{Search for a new heavy gauge boson resonance decaying into a lepton and missing transverse momentum in 36 fb$^{-1}$ of $pp$ collisions at $\sqrt{s} =$ 13 TeV with the ATLAS experiment (Version 1)}", howpublished = "{HEPData (collection)}", year = 2017, note = "\url{https://doi.org/10.17182/hepdata.77273.v1}" }

You can also cite this table directly.

@misc{hepdata.77273.v1/t2, author = "{ATLAS Collaboration}", title = "{``Table 2'' of ``Search for a new heavy gauge boson resonance decaying into a lepton and missing transverse momentum in 36 fb$^{-1}$ of $pp$ collisions at $\sqrt{s} =$ 13 TeV with the ATLAS experiment'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2017, note = "\url{https://doi.org/10.17182/hepdata.77273.v1/t2}" }
