Abstract
This work presents measurements of the transverse-momentum-dependent observable v0(pT) as a novel probe of radial expansion dynamics in Pb-Pb collisions at √sNN = 5.02 TeV with the ALICE detector. Results are reported for inclusive charged hadrons, pions, kaons, and protons across centrality intervals, using a pseudorapidity gap to suppress short-range nonflow correlations. At low pT, a clear mass ordering is observed, consistent with hydrodynamic expectations. For pT > 3 GeV/c, protons exhibit larger v0(pT) than pions and kaons, in line with quark recombination models. These results demonstrate the sensitivity of v0(pT) to collective expansion and hadronization dynamics in the quark-gluon plasma.
