Abstract

We present the invariant yield and elliptic flow of D_\rm_S as a function of transverse momentum in Au+Au collisions at √s_\rmNN = 200 GeV. The nuclear modification factors of D_\rm_S are found to be systematically higher than those of K⁰_\rm_S . The ratio between the yields of strange and non-strange open charm mesons is shown. We find that such a ratio in 0-40% central Au+Au collisions is higher than the fragmentation baseline. Our measurement indicates a substantial enhancement of D_\rm_S production in Au+Au collisions with respect to p+p collisions as compared to non-strange D mesons. The elliptic flow of D_\rm_S is also measured and compared to that of D⁰ as well as model calculations.
