Abstract

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 √s_NN=200\phantom\rule0.3em0exGeV as a function of centrality. The reported values represent the ratio of the yields averaged over the rapidity range of 0.1<y_\ensuremathπ<1.3 and 0<y_K,p<0.8, where positive rapidity is in the deuteron direction, and for transverse momenta 0.1<p_T^\ensuremathπ,K<1\phantom\rule0.3em0exGeV∕c and 0.3<p_T^p<1\phantom\rule0.3em0exGeV∕c. Within the uncertainties, a lack of centrality dependence is observed in all three ratios. The data are compared to results from other systems and model calculations.
