A systematic study of magnetic field in Relativistic Heavy-ion Collisions in the RHIC and LHC energy regions

摘要

The features of magnetic field in relativistic heavy-ion collisions aresystematically studied by using a modified magnetic field model in this paper.The features of magnetic field distributions in the central point are studiedin the RHIC and LHC energy regions. We also predict the feature of magneticfields at LHC $\sqrt{s_{NN}}$= 900, 2760 and 7000 GeV based on the detailedstudy at RHIC $\sqrt{s_{NN}}$ = 62.4, 130 and 200 GeV. The dependencies of thefeatures of magnetic fields on the collision energies, centralities andcollision time are systematically investigated, respectively.
