When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.91630, author = "{CMS Collaboration}", title = "{Measurement of the $\mathrm{t\bar{t}}\mathrm{b\bar{b}}$ production cross section in the all-jet final state in pp collisions at $\sqrt{s} =$ 13 TeV}", howpublished = "{HEPData (collection)}", year = 2020, note = "\url{https://doi.org/10.17182/hepdata.91630}" }

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

@misc{hepdata.91630.v1, author = "{CMS Collaboration}", title = "{Measurement of the $\mathrm{t\bar{t}}\mathrm{b\bar{b}}$ production cross section in the all-jet final state in pp collisions at $\sqrt{s} =$ 13 TeV (Version 1)}", howpublished = "{HEPData (collection)}", year = 2020, note = "\url{https://doi.org/10.17182/hepdata.91630.v1}" }

You can also cite this table directly.

@misc{hepdata.91630.v1/t1, author = "{CMS Collaboration}", title = "{``Table 2'' of ``Measurement of the $\mathrm{t\bar{t}}\mathrm{b\bar{b}}$ production cross section in the all-jet final state in pp collisions at $\sqrt{s} =$ 13 TeV'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2020, note = "\url{https://doi.org/10.17182/hepdata.91630.v1/t1}" }
