When using this data, please cite the original publication:

Additionally, you should cite the record:

@misc{hepdata.93064, author = "{CMS Collaboration}", title = "{Study of excited $\Lambda_\mathrm{b}^0$ states decaying to $\Lambda_\mathrm{b}^0\pi^+\pi^-$ in proton-proton collisions at $\sqrt{s} =$ 13 TeV}", howpublished = "{HEPData (collection)}", year = 2020, note = "\url{https://doi.org/10.17182/hepdata.93064}" }

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

@misc{hepdata.93064.v1, author = "{CMS Collaboration}", title = "{Study of excited $\Lambda_\mathrm{b}^0$ states decaying to $\Lambda_\mathrm{b}^0\pi^+\pi^-$ in proton-proton collisions at $\sqrt{s} =$ 13 TeV (Version 1)}", howpublished = "{HEPData (collection)}", year = 2020, note = "\url{https://doi.org/10.17182/hepdata.93064.v1}" }

You can also cite this table directly.

@misc{hepdata.93064.v1/t2, author = "{CMS Collaboration}", title = "{``Table 2: Mass difference measurements'' of ``Study of excited $\Lambda_\mathrm{b}^0$ states decaying to $\Lambda_\mathrm{b}^0\pi^+\pi^-$ in proton-proton collisions at $\sqrt{s} =$ 13 TeV'' (Version 1)}", howpublished = "{HEPData (dataset)}", year = 2020, note = "\url{https://doi.org/10.17182/hepdata.93064.v1/t2}" }
