===Hyperon capture===
The capture of a Ξ<sup>−</sup> baryon by a nucleus can make a Ξ<sup>−</sup> exotic atom or hypernucleus.<ref name="JPARC E07"/> Upon capture, it changes to a ΛΛ hypernucleus or two Λ hypernuclei.{{sfn|Gal|Hungerford|Millener|2016|p=16,43}} The disadvantage is that the Ξ<sup>−</sup> baryon is harder to make into a beam than singly strange hadrons.{{sfn|Tolos|Fabbietti|2020|p=43}} However, an experiment at [[J-PARC]] begun in 2020 will compile data on Ξ and ΛΛ hypernuclei using a similar, non-beam setup where scattered Ξ<sup>−</sup> baryons rain onto an emulsion target.<ref name="JPARC E07">{{cite journal |last1=Yoshida |first1=J. |collaboration=The J-PARC 07 Collaboration|title=J-PARC E07: Systematic Study of Double Strangeness System with Hybrid Emulsion Method |journal=Proceedings of the 3rd J-PARC Symposium (J-PARC2019) |date=25 March 2021 |volume=33 |page=011112 |doi=10.7566/jpscp.33.011112 |bibcode=2021jprc.confa1112Y |isbn=978-4-89027-146-7 |s2cid=233692057 |doi-access=free }}</ref>
