| Description | Journal: Journal of Physics: Conference Series In this article, we report the measurements of the nuclear modification factor (R$ _{AA}$) and elliptic flow (v$ _{2}$) for in Au+Au collisions at from the STAR experiment. These results are compared with the results of other open charm mesons to study the hadronization mechanism of the charm quarks and disentangle the transport properties of quark-gluon plasma and hadronic phase [1]. We found that the nuclear modification factor for D$ _{s}$ are systematically higher than unity and D$ ^{0}$ R$ _{AA}$. The ratio of D$ _{s}$ /D$ ^{0}$ for 10-40% central Au+Au collisions is also higher than that in p+p collisions as predicted by PYTHIA. The D$ _{s}$ /D$ ^{0}$ ratio is also compared to that in Pb+Pb collisions at measured by the ALICE experiment. Our results indicate an enhancement of D$ _{s}$ meson production in Au+Au collisions. |
