# Layers of quark-gluon plasma induced by chiral magnetic effect and the separation of $u,d$ quarks' critical end points

## TL;DR

This paper proposes that the chiral magnetic effect can induce a layered structure in quark-gluon plasma with distinct critical end points for different quark flavors, offering potential observable signatures to test CME.

## Contribution

It introduces a novel layered model of quark-gluon plasma induced by CME, highlighting flavor-dependent critical end points and potential asymmetries.

## Key findings

- Formation of three distinct layers with different quark chemical potentials.
- Different layers have different critical end points for $u,d$ quarks.
- Possible flavor asymmetry at critical end points under certain conditions.

## Abstract

In this work we show that the chiral magnetic effect (CME) could cause the quark-gluon plasma (QGP) approximately forming three layers along the strong magnetic field characterised by different compositions of quark chemical potentials. This phenomenon may bring new observable outcomes, for example different layers would have different CEPs and the $u,d$ quarks would have different critical end points (CEPs). Since the $s$ quark would make the up and the down layers have some 'asymmetry' on chemical potentials, there is the possibility that at some special conditions one flavor of $u,d$ quarks lies at CEP in one layer but another flavor dose not in any layer. These results may be helpful in testing the existence of CME.
