Centrality dependence of charged antiparticle to particle ratios near midrapidity in d+Au collisions at sNN=200GeV

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 root/s(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 < y(pi) < 1.3 and 0 < y(K,p) <0.8, where positive rapidity is in the deuteron direction, and for transverse momenta 0.1More
