我们研究了集体流对LHC能区电荷相关方位角关联的影响。我们提出了一系列的相关性作为一个签名的方位角集体流动和局部电荷守恒的综合效应，并进行分析内的统计冻结模型。我们发现，目前的LHC测量的电荷依赖的方位角相关的动力学冻结表面上的局部电荷守恒是一致的。鉴于实验搜索的手征磁效应的签名，我们提供了另一种解释所观察到的信号的电荷依赖性，并提出额外的测量解开的影响。
We study the effects of collective flow on charge dependent azimuthal correlations at LHC energies. We propose a series of correlations as a signature of the combined effects of azimuthal collective flow and local charge conservation and perform an analysis within a statistical freeze-out model. We find that present LHC measurements of charge dependent azimuthal correlations are consistent with local charge conservation on the kinetic freeze-out surface. In view of experimental searches for signatures of the chiral-magnetic effect, we provide an alternative explanation of the charge dependence of the observed signal and propose additional measurements to disentangle the effects.
