Abstract
In this article, we report the measurements of the nuclear modification factor (RAA) and elliptic flow (v2) for in Au+Au collisions at from the STAR experiment. These results are compared with the results of other open charm mesons to study the hadronization mechanism of the charm quarks and disentangle the transport properties of quark-gluon plasma and hadronic phase [1]. We found that the nuclear modification factor for Ds are systematically higher than unity and D0 RAA. The ratio of Ds/D0 for 10-40% central Au+Au collisions is also higher than that in p+p collisions as predicted by PYTHIA. The Ds/D0 ratio is also compared to that in Pb+Pb collisions at measured by the ALICE experiment. Our results indicate an enhancement of Ds meson production in Au+Au collisions.
