In search of chiral magnetic effect: separating flow-driven background effects and quantifying anomaly-induced charge separations

TL;DR

This paper advances the search for the Chiral Magnetic Effect by developing new measurement techniques and hydrodynamic simulations to distinguish genuine CME signals from flow-driven background effects in heavy ion collisions.

Contribution

It introduces novel measurement methods and simulation approaches specifically designed to separate CME signals from background effects in experimental data.

Findings

New measurement techniques for CME detection

Hydrodynamic simulations of CME and backgrounds

Improved separation of CME signals from flow effects

Abstract

We report our recent progress on the search of Chiral Magnetic Effect (CME) by developing new measurements as well as by hydrodynamic simulations of CME and background effects, with both approaches addressing the pressing issue of separating flow-driven background contributions and possible CME signal in current heavy ion collision measurements.
