Centrality dependence of charged antiparticle to particle ratios near midrapidity in d+Au collisions at {radical}(s{sub NN})=200 GeV

2004

The ratios of the yields of charged antiparticles to particles have been obtained for pions, kaons, and protons near midrapidity for d+Au collisions at {radical}(s{sub NN})=200 GeV as a function of centrality. The reported values represent the ratio of the yields averaged over the rapidity range of 0.1
