理论认为相对论重离子碰撞实验产生的夸克胶子等离子体（QGP）中可能存在手征反常效应，例如手征磁效应（CME），手征磁波（CMW）和手征涡旋效应（CVE）等。其物理机制与量子色动力学（QCD）真空的新颖拓扑结构和强相互作用下的局域CP对称性相关，意义十分重大，因此相关的实验测量已成为本领域前沿热点。然而，目前多个实验组的测量结果均已经表明观测量中存在巨大的背景，其成分和物理机制尚待进一步研究。基于TeV能区和小系统碰撞中手征反常效应难以产生，因此观测量应由纯背景构成的特点，本项目拟借助LHC-ALICE实验，在TeV能区多个对撞能量和对撞系统下测量相应的观测量，结合唯象模拟，全面研究测量CME，CMW和CVE等手征反常效应的背景来源，阐明这些背景如何通过动力学机制贡献到测量中，这对深入理解非微扰QCD新颖拓扑结构和QGP的集体运动行为具有重要的科学意义。

It is theorized that some anomalous chiral effects, such as chiral magnetic effect, chiral magnetic wave, and chiral vortical effect, could be generated in the Quark-Gluon Plasma (QGP) created by the relativistic heavy-ion collisions. Such effects are of significance since they originally stem from the novel topological nature of the QCD vacuum and are related to the local CP symmetry in the strong interaction. The experimental search for such anomalous chiral effects has been carried out for a decade. In recent years, however, the latest results by different collaborations coincidently indicate considerable backgrounds during the measurements despite their components and mechanisms remain unclear. The CME/CME/CVE measurements at TeV collision energies and in small collision systems are considered to be dominated by pure backgrounds due to lack of environment to generate anomalous chiral effects. Therefore, based on the collisions at various energies (TeV) and systems at LHC-ALICE experiment, we propose to comprehensively investigate the background sources in the measurement of CME, CMW, and CVE, and try to understand the mechanism how they contribute to the observables. This study could provide more experimental evidence and insights for the search of anomalous chiral effects as well as the collective behavior of QGP.
