Study of the correlation of charge separation of the chiral magnetic effect in Relativistic Heavy-ion Collisions
It was pointed out that the chiral magnetic effect is a process of charge separation with respect to the reaction plane. There is one kind of phenomenon of gauge field configurations with nonzero topological charge, which can be a sphaleron in the QCD vacuum. At high temperatures, one expects that the sphaleron process is a dominant process. It is believed that a very strong magnetic field can be produced in relativistic heavy-ion collisions, and it is crucial for charge separation. We calculate the chiral separation effects during RHIC and LHC energy regions by studying the detailed chiral charge separation dependencies on the centralities, collision energies and nuclear screening effects in the paper. The response of QGP medium to magnetic field is introduced in the discussion, which help us to study the features of chiral magnetic field and QGP in relativistic heavy-ion collisions.
