标题： Charge-dependent azimuthal correlations from AuAu to UU collisions

摘要： 我们研究相对论重离子碰撞中的电荷依赖的方位角关联，这是为了寻找手征磁效应（CME）以及研究相关的背景贡献。 特别是我们旨在理解由各种提出的效应引起的这些关联如何从AuAu系统碰撞演化到UU系统碰撞。 为此，我们通过逐事件模拟量化了RHIC能量下UU碰撞中产生的磁场及其与物质几何结构的方位角关联。 利用来自AuAu碰撞的电荷依赖的方位角关联的实验数据，并做出合理的假设将其外推到UU碰撞，我们检验了UU碰撞中预期的关联，并与最近的STAR测量结果进行比较。 基于这种分析，我们讨论了通过CME类似和流诱导贡献的组合来解释数据的可行性。 显示英文摘要

摘要： We study the charge-dependent azimuthal correlations in relativistic heavy ion collisions, as motivated by the search for the Chiral Magnetic Effect (CME) and the investigation of related background contributions. In particular we aim to understand how these correlations induced by various proposed effects evolve from collisions with AuAu system to that with UU system. To do that, we quantify the generation of magnetic field in UU collisions at RHIC energy and its azimuthal correlation to the matter geometry using event-by-event simulations. Taking the experimental data for charge-dependent azimuthal correlations from AuAu collisions and extrapolating to UU with reasonable assumptions, we examine the resulting correlations to be expected in UU collisions and compare them with recent STAR measurements. Based on such analysis we discuss the viability for explaining the data with a combination of the CME-like and flow-induced contributions.
