Contribution

First measurement of open charm cross-section in heavy-ion collisions at RHIC using multiple decay channels, providing insights into medium effects.

Findings

Open charm production consistent with pQCD predictions.

Evidence of medium-induced energy loss from $R_{AA}$ analysis.

Quantitative cross-section measurements for open charm.

Abstract

We report on measurements of open charm production through both hadronic and semi-leptonic decay channels in $\sqrt{s_{NN}}$ = 200 GeV heavy ion collision at the STAR experiment at RHIC. We compare experimental results to theoretical predictions from pQCD. The open charm $R_{AA}$ is also presented as evidence of possible medium-induced energy loss.
