A fit to the measured proton-proton correlation functions allows one to extract the dependence of the nucleon femtoscopic radius of the particle-emitting source as a function of the pair transverse mass ($m_\\text{T}$) and of the average charge particle multiplicity $\\langle\\text{dN}_\\text{ch}/\\text{d}\\eta\\rangle^{1/3}$ for three centrality intervals (0--10$\\%$, 10--30$\\%$, 30--50$\\%$). In both cases, the expected power-law and liner scalings are observed, respectively. The measured \\pd correlations can be described by both two- and three-body calculations, indicating that the femtoscopy observable is not sensitive to the short-distance features of the dynamics of the p-(p-n) system, due to the large inter-particle distances in \\mbox{Pb--Pb} collisions at the LHC. Indeed, in this study, the minimum measured femtoscopic source sizes for protons and deuterons start at $2.73^{+0.05}_{-0.05}$ and $3.10^{+1.04}_{-0.86}$~fm, respectively, for the 30\u201350$\\%$ centrality of the collisions. Moreover, the $m_{\\rm{T}}$-scaling obtained for the \\pP and \\pd systems is compatible within 1$\\sigma$ of the uncertainties. These findings provide new input for fundamental studies on the production of light (anti)nuclei under extreme conditions.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.165812.v1/t1","@type":"Dataset","description":"proton-proton (same charge) correlation function for centrality 0-10% from Pb-Pb
