Electromagnetic field from asymmetric to symmetric heavy-ion collisions at 200 GeV/c.

Electromagnetic fields produced in relativistic heavy-ion collisions are affected by the asymmetry of the projectile-target combination as well as the different initial configurations of the nucleus. In this study, the results of the electric and magnetic fields produced for different combinations of ions, namely 12C+197Au, 24Mg+197Au, 64Cu+197Au, and 197Au+197Au at √sNN=200 GeV, are demonstrated with a multiphase transport model. The configuration of the distribution of nucleons of 12C is initialized by a Woods-Saxon spherical structure, a three-α-clustering triangular structure or a three-α-clustering chain structure. It was observed that the electric and magnetic fields display different behavioral patterns for asymmetric combinations of the projectile and target nuclei as well as for different initial configurations of the carbon nucleus. The major features of the process are discussed. [ABSTRACT FROM AUTHOR]
