When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.60276, author = "{ATLAS Collaboration}", title = "{Search for Supersymmetry in Events with Large Missing Transverse Momentum, Jets, and at Least One Tau Lepton in 7 TeV Proton-Proton Collision Data with the ATLAS Detector}", howpublished = "{HEPData (collection)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.60276}" }

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

@misc{hepdata.60276.v1, author = "{ATLAS Collaboration}", title = "{Search for Supersymmetry in Events with Large Missing Transverse Momentum, Jets, and at Least One Tau Lepton in 7 TeV Proton-Proton Collision Data with the ATLAS Detector (Version 1)}", howpublished = "{HEPData (collection)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.60276.v1}" }

You can also cite this table directly.

@misc{hepdata.60276.v1/t3, author = "{ATLAS Collaboration}", title = "{``Table 3'' of ``Search for Supersymmetry in Events with Large Missing Transverse Momentum, Jets, and at Least One Tau Lepton in 7 TeV Proton-Proton Collision Data with the ATLAS Detector'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2013, note = "\url{https://doi.org/10.17182/hepdata.60276.v1/t3}" }
