When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.70230, author = "{CMS Collaboration}", title = "{Measurement of spin correlations in t t-bar production using the matrix element method in the muon + jets final state in pp collisions at sqrt(s) = 8 TeV}", howpublished = "{HEPData (collection)}", year = 2015, note = "\url{https://doi.org/10.17182/hepdata.70230}" }

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

@misc{hepdata.70230.v1, author = "{CMS Collaboration}", title = "{Measurement of spin correlations in t t-bar production using the matrix element method in the muon + jets final state in pp collisions at sqrt(s) = 8 TeV (Version 1)}", howpublished = "{HEPData (collection)}", year = 2015, note = "\url{https://doi.org/10.17182/hepdata.70230.v1}" }

You can also cite the 1 data table individually.
