   Abstract:
   This work reports femtoscopic correlations of p-−p(p‾-−p‾) and p−−d(p‾-−d‾) pairs measured in Pb–Pb collisions at center-of-mass energy per nucleon sNN = 5.02 TeV in the ALICE Collaboration. 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 on the pair transverse mass (mT) and on the average charge particle multiplicity 〈dNch/dη〉^1/3 for three centrality intervals (0–10%,10−−30%,30−−50%). In both cases, the expected power-law and linear scalings are observed, respectively. The measured p–d 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 Pb–Pb collisions at the LHC. Indeed, in this study, the minimum measured femtoscopic source sizes for protons and deuterons have a minimum value at 2.73−0.05^+0.05 and 3.10−0.86^+1.04 fm, respectively, for the 30–50% centrality collisions. Moreover, the m T-scaling obtained for the p–p and p–d systems is compatible within 1 σ of the uncertainties. These findings provide new input for fundamental studies on the production of light (anti)nuclei under extreme conditions.
