Using the Statistical Hadronization framework, it is possible to obtain the value of the electric charge and baryon chemical potentials, $\\mu_Q=-0.18\\pm0.90$ MeV and $\\mu_B=0.71\\pm0.45$ MeV, with unprecedented precision. A centrality-differential study of the antiparticle-to-particle yield ratios of charged pions, protons, $\\Omega$-baryons, and light (hyper)nuclei is performed. These results indicate that the system created in Pb-Pb collisions at the LHC is on average baryon-free and electrically neutral at midrapidity.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.151650.v1/t1","@type":"Dataset","description":"Antiparticle-to-particle yield ratio, 0-5% centrality","name":"Ratios
