The chiral magnetic effect in heavy-ion collisions from event-by-event anomalous hydrodynamics

TL;DR

This paper uses advanced relativistic hydrodynamics to quantitatively analyze the chiral magnetic effect in heavy-ion collisions, showing that charge-dependent correlations align with experimental data.

Contribution

It introduces a (3+1)D anomalous hydrodynamics framework to model the CME in heavy-ion collisions, providing a quantitative match with observations.

Findings

Charge-dependent azimuthal correlations are sensitive to the CME.

Experimental data is consistent with the presence of the CME.

The hydrodynamics model successfully describes the observed phenomena.

Abstract

The (3+1)D relativistic hydrodynamics with chiral anomaly is used to obtain a quantitative description of the chiral magnetic effect (CME) in heavy-ion collisions. We find that the charge-dependent hadron azimuthal correlations are sensitive to the CME, and that the experimental observations are consistent with the presence of the effect.
