When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.86228, author = "{CMS Collaboration}", title = "{Search for an exotic decay of the Higgs boson to a pair of light pseudoscalars in the final state with two b quarks and two $\tau$ leptons in proton-proton collisions at $\sqrt{s}=$ 13 TeV}", howpublished = "{HEPData (collection)}", year = 2018, note = "\url{https://doi.org/10.17182/hepdata.86228}" }

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

@misc{hepdata.86228.v1, author = "{CMS Collaboration}", title = "{Search for an exotic decay of the Higgs boson to a pair of light pseudoscalars in the final state with two b quarks and two $\tau$ leptons in proton-proton collisions at $\sqrt{s}=$ 13 TeV (Version 1)}", howpublished = "{HEPData (collection)}", year = 2018, note = "\url{https://doi.org/10.17182/hepdata.86228.v1}" }

You can also cite the 1 data table individually.
