在量子色动力学中，具有非零拓扑荷的规范场组态会产生左手夸克和右手夸克的数量之差。当一个（电磁）磁场被加到这个结构上时，一个电磁电流会沿着磁场被感应出来，这被称为手征磁效应。我们计算了这种电流的存在下，具有拓扑电荷的色通量管，与磁场施加垂直it.We认为，这种情况是实现在相对论重离子碰撞的早期阶段。
In quantum chromodynamics, a gauge field configuration with nonzero topological charge generates a difference between the number of left- and right-handed quarks. When a (electromagnetic) magnetic field is added to this configuration, an electromagnetic current is induced along the magnetic field; this is called the chiral magnetic effect. We compute this current in the presence of a color-flux tube possessing topological charge, with a magnetic field applied perpendicular to it. We argue that this situation is realized at the early stage of relativistic heavy-ion collisions.
