Abstract

The ratios of the yields of primary charged antiparticles to particles have been obtained for pions, kaons, and protons near midrapidity for p + p collisions at √s_NN = 200 GeV. Ratios of (π^-/ π⁺) = 1.000 ± 0.012 (stat.) ± 0.019 (syst.), (K ^-/K⁺) = 0.93 ± 0.05 (stat.) ± 0.03 (syst.), and (p̄/p) = 0.85 ± 0.04 (stat.) ± 0.03 (syst.) have been measured. The reported values represent the ratio of the yields averaged over the rapidity range of 0.1 < y_π < 1.3 and 0 < y _K,p < 0.8, and for transverse momenta of 0.1 < p _T^π,K < 1.0 GeV/c and 0.3 < p_T ^p < 1.0 GeV/c. Within the uncertainties, all three ratios are consistent with the values measured in d + Au collisions at the same energy. The data are compared to results from other collision systems and energies.
