在量子色动力学中，夸克与拓扑胶子场的相互作用可以导致局域P和CP破坏，这可能为强CP问题提供一个解决方案，并为解释当前宇宙中物质对物质的不对称性提供了可能。在强磁场作用下，P和CP破坏将导致粒子按电荷分离，这被称为手征磁效应（CME）。对日冕物质抛射引起的电荷分离的观测将证实QCD的几个基本性质，即近似手征对称性恢复、拓扑电荷涨落和局域宇称破坏。在相对论重离子碰撞中，还有其他类似于CME的手征反常效应，如手征涡旋效应（CVE）和手征磁波（CMW）。本文综述了相对论重离子碰撞中CME、CVE和CMW研究的最新进展。
In quantum chromodynamics, the interactions of quarks with the topological gluon fields can lead to local P and CP violations, which may provide a solution to the strong CP problem and a possibility to explain the asymmetry of matterantimatter in the current universe. Under a strong magnetic field, the P and CP violations will lead to the separation of particles according to their electric charges, which is called the chiral magnetic effect (CME). An observation of the CMEinduced charge separation would confirm several fundamental properties of QCD, namely, approximate chiral symmetry restoration, topological charge fluctuations, and local parity violation. In relativistic heavy-ion collisions, there are other chiral anomalous effects similar to the CME, such as the chiral vortical effect (CVE), and the chiral magnetic wave (CMW). This review briefly summarizes the current experimental progress of the CME, CVE, and CMW searches in relativistic heavyion collisions.
