We report the first measurement of charmed-hadron ($D^0$) production via the hadronic decay channel ($D^0\\rightarrow K^- + \\pi^+$) in Au+Au collisions at $\\sqrt{s_{_{\\mathrm{NN}}}}$ = 200 GeV with the STAR experiment. The charm production cross-section per nucleon-nucleon collision at mid-rapidity scales with the number of binary collisions, $N_{\\mathrm{bin}}$, from p+p to central Au+Au collisions. The $D^0$ meson yields in central Au+Au collisions are strongly suppressed compared to those in p+p scaled by $N_{\\mathrm{bin}}$, for transverse momenta $p_{T}>3$ GeV/$c$, demonstrating significant energy loss of charm quarks in the hot and dense medium. An enhancement at intermediate $p_{\\rm T}$ is also observed. Model calculations including strong charm-medium interactions and coalescence hadronization describe our measurements.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.73474.v3/t1","@type":"Dataset","description":"$D^0$ $p_{\\rm T}$ differential invariant yield in p+p collisions (open circles), which has been updated with the latest global analysis...","name":"Table 0"},{"@id":"https://doi.org/10.17182/hepdata.73474.v3/t2","@type":"Dataset","description":"Centrality dependence of the $D^0$ $p_{\\rm T}$ differential invariant yield in Au+Au collisions (solid symbols).
