论文摘要
在先进的Langevin-Hydrodnymics框架中，与混合片段化 - 钙化强化模型结合在一起，我们研究了相对论重离子碰撞中的重风味和流动。我们研究了介质中重夸克的初始重夸克光谱，能量损失和强调机制如何，平衡阶段的演化曲线，培养基流动以及重夸克扩散系数的温度依赖性影响了rhIC和LHC的重脑子的抑制和椭圆流动。我们的结果表明，初始条件，平衡前进化和中等相互作用的不同建模可以单独产生约10-40％的不确定性，而在低横向动量下的D介质抑制和流动。我们还发现，碰撞与辐射能量损失，结合与碎片化的适当组合以及中等流动的包含是描述重介子的抑制和椭圆流的最重要因素。
Within an advanced Langevin-hydrodynamics framework coupled to a hybrid fragmentation-coalescence hadronization model, we study heavy flavor quenching and flow in relativistic heavy-ion collisions. We investigate how the initial heavy quark spectrum, the energy loss and hadronization mechanisms of heavy quarks in medium, the evolution profile of pre-equilibrium stage, the flow of medium and the temperature dependence of heavy quark diffusion coefficient influence the suppression and elliptic flow of heavy mesons at RHIC and the LHC. Our result shows that different modeling of initial conditions, pre-equilibrium evolution and in-medium interaction can individually yield about 10-40% uncertainties in D meson suppression and flow at low transverse momentum. We also find that a proper combination of collisional versus radiative energy loss, coalescence versus fragmentation in hadronization, and the inclusion of medium flow are the most important factors for describing the suppression and elliptic flow of heavy mesons.
