Unbound ensembles composed of a deuteron and a third nucleon have been investigated in the past using scattering experiments and they constitute a fundamental reference in nuclear physics to constrain nuclear interactions and the properties of nuclei. In this work K$^{+}$--d and p--d femtoscopic correlations measured  by the ALICE Collaboration in proton--proton (pp) collisions at $\\sqrt{s}=13$~TeV at the Large Hadron Collider (LHC) are presented. It is demonstrated that correlations in momentum space between deuterons and kaons or protons allow us to study three-hadron systems at distances comparable with the proton radius. The analysis of the K$^{+}$--d correlation shows that the relative distances at which deuterons and proton/kaons are produced are around 2 fm. The analysis of the p--d correlation shows that only a full three-body calculation that accounts for the internal structure of the deuteron can explain the data. In particular, the sensitivity of the observable to the short-range part of the interaction is demonstrated. These results indicate that correlations involving light nuclei in pp collisions at the LHC will also provide access to any three-body systems in the strange and charm sectors.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.153726.v1/t1","@type":"Dataset","description":"The K$^{+}$--d $\\oplus$ K$^{-}$--$\\overline{\\mathrm{d}}$ correlation function as a function of $k^*$.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.153726.v1/t2","@type":"Dataset","description":"The p--d $\\oplus$ $\\overline{\\mathrm{p}}$--$\\overline{\\mathrm{d}}$ correlation function as a function of $k^*$.","name":"Table 2"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2691844?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/153726"}],"inLanguage":"en","name":"Exploring the strong interaction of three-body systems at the LHC","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2691844?version=1","version":1}
