A brief discussion on the chiral magnetic effect

Abstract

The prerequisite of the chiral magnetic effect is the existence of net chiral charge in the quark gluon plasma (QGP). If we assume the quarks and anti-quarks contribute equally to the net chiral charge, the CME will induce a flow of the quark chemical potential and will cause the QGP having three distinct layers along the strong magnetic field characterised by distinctive compositions of quark chemical potentials. This phenomenon may bring new observable outcomes and help us test the existence of CME.
