Measurements of chemical potentials in Pb-Pb collisions at sqrt{s_(rm NN)} = 5.02 TeV
read the original abstract
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 $\sqrt{s_{\rm NN}} = 5.02$ TeV. 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.

$\Lambda$(1520) as a probe of resonance-driven deuteron formation at the LHC
Simulations show a peak in the proxy mass M_(d/2)K only when deuterons form by coalescence of protons from Λ(1520) decays, not in thermal models.
