# A brief discussion on the chiral magnetic effect

## TL;DR

This paper discusses the conditions and potential observable effects of the chiral magnetic effect in quark-gluon plasma, emphasizing the role of net chiral charge and layered structures under strong magnetic fields.

## Contribution

It provides a theoretical discussion on the layered structure formation in QGP due to CME and suggests new observable signatures for experimental testing.

## Key findings

- QGP can develop three distinct layers with different quark chemical potentials
- Net chiral charge is essential for the manifestation of CME
- Layered structures could serve as experimental signatures of CME

## 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.
