The effect of the magnetic field in the heavy-ion collision

• Seyed Mohammad Ali Tabatabaee Mehr (IPM)

In the collision of heavy ions, due to the fast-moving charged particles, a strong magnetic field of the order of 10^{18-20} Gauss is expected to be generated. In the presence of such a strong magnetic field, several novel phenomena like Magnetic catalysis of chiral symmetry restoration, the chiral magnetic effect may arise. Therefore, the knowledge of the evolution of the magnetic field, its lifetime, and possible effects on the plasma is of primary interest. In this talk, I start with a short overview of the properties of the generated magnetic field. Then I will consider the interaction of the spin of the constituent particles with the background magnetic field. This leads to a finite magnetization. Finite magnetization causes anisotropy in the pressure of the system. In this case, using the quantum kinetic theory the effect of finite magnetization on the evolution of plasma will be discussed.. Finally, I will present part of the results obtained in Phys.Rev.D 101 (2020) 7, 076022.
