论文摘要
手性异常意味着存在非疾病的转运现象，例如手性磁效应。在衍生膨胀的二阶，新型量子转运现象出现。在本文中，我们专注于剪切，涡度和磁场的组合驱动的异常运输。我们发现，相应的转运现象 - 剪切诱导的手性磁和手性涡旋效应（SICME和SICVE） - 诱导重离子碰撞中产生的黑龙之间的特性电荷相关性。我们提出了三角形流的电荷不对称性作为异常运输的特征，并使用流体动力学模型模拟估计信号的强度以及背景的强度。我们发现，所提出的可观察到的信噪比比率有利于实验检测。
Chiral anomaly implies the existence of non-dissipative transport phenomena, such as the chiral magnetic effect. At second order in the derivative expansion, novel quantum transport phenomena emerge. In this paper, we focus on the anomalous transport driven by a combination of shear, vorticity and magnetic field. We find that the corresponding transport phenomena -- shear-induced chiral magnetic and chiral vortical effects (siCME and siCVE) -- induce characteristic charge correlations among the hadrons produced in heavy ion collisions. We propose the charge asymmetry of triangular flow as a signature of the anomalous transport, and estimate the strength of the signal, as well as the background, using hydrodynamical model simulations. We find that the signal-to-background ratio for the proposed observable is favorable for experimental detection.
