论文摘要

运输计算代表了模拟高能核碰撞中的重型流动颗粒时,由热固定介质存在的修改所引起的修改。在对方法和现象学应用中的主要成就进行了简要描述之后,我们讨论了一些最近的发展。特别是,我们专注于在沉积能量分布(奇数流谐波,事件形状工程)的分布中以及初始几何学相对于梁轴(有向流)的倾斜而引起的可观察到的,并具有由旁观者核子产生的强磁场所起的作用。

Transport calculations represent the major tool to simulate the modifications induced by the presence of a hot-deconfined medium on the production of heavy-flavour particles in high-energy nuclear collisions. After a brief description of the approach and of the major achievements in its phenomenological applications we discuss some recent developments. In particular we focus on observables arising from event-by-event fluctuations in the distribution of deposited energy (odd flow harmonics, event-shape-engineering) and from the tilting of the initial geometry with respect to the beam axis (directed flow), with a possible role played by the strong magnetic field generated by the spectator nucleons.
