# Chiral magnetic effect in isobaric collisions

## TL;DR

This paper uses numerical simulations of isobaric nuclear collisions to investigate the chiral magnetic effect, aiming to distinguish CME signals from background effects and explore additional phenomena.

## Contribution

It demonstrates that isobaric collisions are an effective method to isolate the CME signal from background effects in high-energy nuclear collisions.

## Key findings

- Isobaric collisions can effectively separate CME signals from background effects.
- Simulations show measurable charge separation differences between Ru+Ru and Zr+Zr collisions.
- Additional effects in isobaric collisions can be tested to understand underlying physics.

## Abstract

We give a numerical simulation of the generation of the magnetic field and the charge-separation signal due to the chiral magnetic effect (CME) --- the induction of an electric current by the magnetic field in a parity-odd matter --- in the collisions of isobaric nuclei, $^{96}_{44}$Ru + $^{96}_{44}$Ru and $^{96}_{40}$Zr + $^{96}_{40}$Zr, at $\sqrt{s_{\rm NN}}=200$ GeV. We show that such collisions provide an ideal tool to disentangle the CME signal from the possible elliptic-flow driven background effects. We also discuss some other effects that can be tested by using the isobaric collisions.
