标题： Resolving the $R_{AA}$ to $v_n$ puzzle

摘要： 经过十年的努力，试图同时描述高 $p_T$ 下的核修正因子 $R_{AA}$ 和流谐波 $v_n$，如今理论模型已能很好地再现实验数据。 综述了必要的理论发展，例如事件级涨落、初始条件的选择以及用于计算高 $p_T$ 流谐波的标量积方法。 此外，还包括对新提出的称为软硬事件工程（SHEE）的实验可观测量的讨论，这些可观测量对能量损失的路径长度依赖性敏感。 显示英文摘要

摘要： After 10 years of struggling to simultaneously describe the nuclear modification factor $R_{AA}$ and flow harmonics $v_n$'s at high $p_T$, now theoretical models are able to reproduce experimental data well. The necessary theoretical developments such as event-by-event fluctuations, choice of initial conditions, and the scalar product method to calculate flow harmonics at high $p_T$ are reviewed. Additionally, a discussion of new proposed experimental observables known as Soft Hard Event Engineering (SHEE) that are sensitive to the path length dependence of the energy loss is included.
