摘要:

磁场在相对论重离子碰撞中手征磁效应的研究中起着重要的作用。如果磁场的寿命太短,如通过真空中的场的模拟所预期的,手征磁效应将在很大程度上被抑制。但考虑QGP介质响应后,磁场的寿命将变长。考虑到QGP介质的磁场响应,我们给出了这种效应的估计,并与RHIC和LHC能区背景扣除相关器$H$的实验结果进行了比较。结果表明,我们的方法在RHIC顶能区比在LHC顶能区更好地解释了实验结果。

英文摘要:

The magnetic field plays a major role in the searching of the chiral magnetic effect in relativistic heavy-ion collisions. If the lifetime of the magnetic field is too short, as expected by simulations of the field in the vacuum, the chiral magnetic effect will be largely suppressed. However, the lifetime of the magnetic field will become longer when the QGP medium response is considered. We give an estimate of the effect, especially considering the magnetic field response of the QGP medium, and compare it with the experimental results of background-subtracted correlator $H$ at RHIC and LHC energies. The results show that our method explains better for the experimental results at the top RHIC energy than that of the LHC energy.
