反常- Viscous Fluid动力学（AVFD）中等压碰撞的手征磁效应
Chiral Magnetic Effect in Isobaric Collisions from Anomalous-Viscous Fluid Dynamics (AVFD)
摘要：
RHIC的等压碰撞实验为探测重离子碰撞中可能存在的手征磁效应（CME）信号提供了独特的机会。这个想法是为了对比两个碰撞系统的相关观测值，这两个碰撞系统应该具有相同的流动驱动背景贡献，而由于它们的核电荷和磁场强度的10%变化，CME信号贡献非常不同。与最近开发的定量模拟工具计算CME信号，异常粘性流体动力学（AVFD），我们证明了联合（多重性+椭圆流）事件的选择是至关重要的，为此目的。我们进一步建议使用RuRu和ZrZr事件之间的绝对差异（使用相同的事件选择后）检测CME信号，并对相关观测值进行预测。
英文摘要：
The isobaric collision experiment at RHIC provides the unique opportunity to detect the possible signal of Chiral Magnetic Effect (CME) in heavy ion collisions. The idea is to contrast the correlation observables of the two colliding systems that supposedly have identical flow-driven background contributions while quite different CME signal contributions due to the 10% variation in their nuclear charge and thus magnetic field strength. With the recently developed quantitative simulation tool for computing CME signal, the Anomalous-Viscous Fluid Dynamics (AVFD), we demonstrate that a joint (multiplicity + elliptic-flow) event selection is crucial for this purpose. We further propose to use the absolute difference between RuRu and ZrZr events (after using identical event selection) for detecting CME signal and make predictions for the correlation observables.
