When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.95232, author = "{CMS Collaboration}", title = "{Observation of B$^0_s$ mesons and measurement of the B$^0_s$/B$^+$ yield ratio in PbPb collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV}", howpublished = "{HEPData (collection)}", year = 2021, note = "\url{https://doi.org/10.17182/hepdata.95232}" }

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

@misc{hepdata.95232.v1, author = "{CMS Collaboration}", title = "{Observation of B$^0_s$ mesons and measurement of the B$^0_s$/B$^+$ yield ratio in PbPb collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV (Version 1)}", howpublished = "{HEPData (collection)}", year = 2021, note = "\url{https://doi.org/10.17182/hepdata.95232.v1}" }

You can also cite this table directly.

@misc{hepdata.95232.v1/t6, author = "{CMS Collaboration}", title = "{``Table 6'' of ``Observation of B$^0_s$ mesons and measurement of the B$^0_s$/B$^+$ yield ratio in PbPb collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2021, note = "\url{https://doi.org/10.17182/hepdata.95232.v1/t6}" }
