abstract = "We have measured the ratios of antiparticles to particles for charged pions, kaons, and protons near mid-rapidity in central Au+Au collisions at √sNN = 130 GeV. We observe ⟨π-⟩/⟨π+⟩ = 1.00±0.01(stat)±0.02(syst), ⟨K-⟩/⟨K+⟩ = 0.91±0.07(stat)±0.06(syst), and ⟨p¯⟩/⟨p⟩ = 0.60±0.04(stat)±0.06(syst). The ⟨K-⟩/⟨K+⟩ and ⟨p¯⟩/⟨p⟩ ratios give a consistent estimate of the baryo-chemical potential μB of 45 MeV, a factor of 5-6 smaller than in central Pb+Pb collisions at √sNN = 17.2 GeV.",
