论文摘要
像魅力和美容一样，重型夸克是研究Quark-Gluon等离子体（QGP）中颜色固定的培养基的敏感探针。爱丽丝合作测量了d $^{0} $，d $^{+} $的产生，d $^{*+} $和d $ _ {\ mathrm {s}}}^{+} $在$ \ sqrt {核修饰因子的测量（$ r _ {\ rm {aa}} $）提供了有关中等内部能量损失的信息。此外，d $ _ {\ mathrm {s}}}^{+} $与非震动d-Meson $ r _ {\ rm {aa}} $之间的比较允许调查QGP中的Charm-Quark Hadronisation机制的可能修改。这些可观测物的最新结果是通过分析最新的2018年PB-PB碰撞数据样本获得的，以及与理论模型计算的比较。
Heavy quarks, like charm and beauty, are sensitive probes to investigate the colour-deconfined medium created in high-energy heavy-ion collisions, the Quark-Gluon Plasma (QGP). The ALICE Collaboration measured the production of D$^{0}$, D$^{+}$, D$^{*+}$ and D$_{\mathrm{s}}^{+}$ in Pb-Pb collisions at $\sqrt{s_{\rm {NN}}}$ = 5.02 TeV. The measurement of the nuclear modification factor ($R_{\rm {AA}}$) provides informations on the in-medium parton energy loss. In addition, the comparison between D$_{\mathrm{s}}^{+}$ and the non-strange D-meson $R_{\rm {AA}}$ allows to investigate possible modifications of the charm-quark hadronisation mechanism in the QGP. The most recent results for these observables, which were obtained by analysing the latest 2018 data sample of Pb-Pb collisions, are presented as well as the comparison with theoretical model calculations.
