This Letter presents the most precise measurement to date of the matter-antimatter imbalance at midrapidity in Pb-Pb collisions at a center-of-mass energy per nucleon pair sqrt[s_{NN}]=5.02 TeV. Using the Statistical Hadronization framework, it is possible to obtain the value of the electric charge and baryon chemical potentials, μ_{Q}=-0.18±0.90 MeV and μ_{B}=0.71±0.45 MeV, with unprecedented precision. A centrality-differential study of the antiparticle-to-particle yield ratios of charged pions, protons, Ω 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.
本信函展示了迄今为止对质心能量为每核子对(\sqrt[s_{NN}]=5.02) TeV的铅-铅碰撞中快度中间区域物质-反物质失衡的最精确测量。利用统计强子化框架，可以以前所未有的精度获得电荷和重子化学势的值，(\mu_{Q}=-0.18\pm0.90) MeV和(\mu_{B}=0.71\pm0.45) MeV。对带电π介子、质子、Ω重子和轻（超）核的反粒子与粒子产率比进行了中心度微分研究。这些结果表明，大型强子对撞机中铅-铅碰撞产生的系统在快度中间区域平均而言是无重子且电中性的。
