【 摘 要 】

We report on the STAR measurements of open charm hadron and heavy flavor decay electron (NPE) production in Au+Au collisions atSNN = 200 GeV. The centrality dependences of D-meson and NPE pT spectra, nuclear modification factors as well as the NPE elliptic flow v2 are presented. The model comparisons and interpreted physics are discussed.
