Please find below title and abstract. | | Cheers, | | Gunther | | | "Centrality dependence of charged antiparticle to particle ratios near | mid-rapidity in d+Au collisions at sqrt(s_NN) = 200 GeV | | The ratios of the yields of charged antiparticles to particles have been | obtained for pions, kaons, and protons near mid-rapidity for d+Au | collisions at sqrt(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 | 0.1<p_T^(pi,K)<1.0 GeV/c and 0.3<p_T^p<1.0 GeV/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." | | | |
