标题： Heavy flavours in high-energy nuclear collisions: quenching, flow and correlations

摘要： 我们展示了通过POWLANG输运设置获得的高能核-核碰撞中重味粒子的淬火、椭圆流和方位角关联的结果，该设置在过去开发用于研究重夸克在夸克-胶子等离子体中的传播，并在此扩展以包括在介质存在下其强子化的建模。 强子化被描述为通过带有端点由重(反)夸克Q(Qbar)和来自介质的热部分子$qbar(q)$的弦的碎片化来发生。 显示轻夸克的流显著影响最终D介子的R_AA和v_2，从而与实验数据更好地一致。 显示英文摘要

摘要： We present results for the quenching, elliptic flow and azimuthal correlations of heavy flavour particles in high-energy nucleus-nucleus collisions obtained through the POWLANG transport setup, developed in the past to study the propagation of heavy quarks in the Quark-Gluon Plasma and here extended to include a modeling of their hadronization in the presence of a medium. Hadronization is described as occurring via the fragmentation of strings with endpoints given by the heavy (anti-)quark Q(Qbar) and a thermal parton $qbar(q)$ from the medium. The flow of the light quarks is shown to affect significantly the R_AA} and v_2 of the final D mesons, leading to a better agreement with the experimental data.
