# Quantifying the Chiral Magnetic Effect from Anomalous-Viscous Fluid Dynamics

## TL;DR

This paper introduces the AVFD framework to simulate fermion currents in quark-gluon plasma, successfully matching experimental CME signals and predicting outcomes for upcoming isobaric collision experiments.

## Contribution

The paper develops a novel anomalous-viscous fluid dynamics model that quantitatively describes the chiral magnetic effect in heavy ion collisions.

## Key findings

- CME signal predictions align with RHIC data.
- Event-by-event simulations enable background separation.
- Predictions for isobaric collisions offer a critical test of CME.

## Abstract

In this contribution we report a recently developed Anomalous-Viscous Fluid Dynamics (AVFD) framework, which simulates the evolution of fermion currents in QGP on top of the bulk expansion from data-validated VISHNU hydrodynamics. With reasonable estimates of initial conditions and magnetic field lifetime, the predicted CME signal is quantitatively consistent with change separation measurements in 200GeV Au-Au collisions at RHIC. We further develop the event-by-event AVFD simulations that allow direct evaluation of two-particle correlations arising from CME signal as well as the non-CME backgrounds. Finally we report predictions from AVFD simulations for the upcoming isobaric (Ru-Ru v.s. Zr-Zr ) collisions that could provide the critical test of the CME in heavy ion collisions.
