在夸克-胶子等离子体(QGP)中，电场可以导致手性分离。这就是手性电分离效应。在偏心核-核碰撞中，完全可以产生强电磁场和QCD真空。我们使用Wood-Saxon核子分布来计算离心碰撞的电场分布。本文系统地研究了相对论重离子对撞机(RHIC)和大型强子对撞机(LHC)能区的手征电场空间分布。本文研究了在RHIC能区和LHC能区，不同碰撞参数的中心位置的热夸克产生的电场对不同碰撞能量的适当时间的依赖关系。
It has been proposed that electric fields may lead to chiral separation in quark-gluon plasma (QGP). This is called the chiral electric separation effect. The strong electromagnetic field and the QCD vacuum can both be completely produced in off-central nuclear-nuclear collision. We use the Woods-Saxon nucleon distribution to calculate the electric field distributions of off-central collisions. The chiral electric field spatial distribution at Relativistic Heavy-Ion Collider (RHIC) and Large Hadron Collider (LHC) energy regions are systematically studied in this paper. The dependence of the electric field produced by the thermal quark in the central position with different impact parameters on the proper time with different collision energies in the RHIC and LHC energy regions are studied in this paper.
