When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.57953, author = "{CMS Collaboration}", title = "{Measurement of W+W- Production and Search for the Higgs Boson in pp Collisions at sqrt(s) = 7 TeV}", howpublished = "{HEPData (collection)}", year = 2011, note = "\url{https://doi.org/10.17182/hepdata.57953}" }

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

@misc{hepdata.57953.v1, author = "{CMS Collaboration}", title = "{Measurement of W+W- Production and Search for the Higgs Boson in pp Collisions at sqrt(s) = 7 TeV (Version 1)}", howpublished = "{HEPData (collection)}", year = 2011, note = "\url{https://doi.org/10.17182/hepdata.57953.v1}" }

You can also cite this table directly.

@misc{hepdata.57953.v1/t1, author = "{CMS Collaboration}", title = "{``Table 1'' of ``Measurement of W+W- Production and Search for the Higgs Boson in pp Collisions at sqrt(s) = 7 TeV'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2011, note = "\url{https://doi.org/10.17182/hepdata.57953.v1/t1}" }
