# Event-by-event charge separation in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV with ALICE at the LHC

## TL;DR

This paper investigates charge separation phenomena in Pb-Pb collisions at 2.76 TeV using an event-by-event analysis method to explore potential signs of parity violation in relativistic heavy-ion collisions.

## Contribution

It introduces the Sliding Dumbbell Method (SDM) for event-by-event measurement of charge separation in heavy-ion collisions, a novel approach in this context.

## Key findings

- First application of SDM in Pb-Pb collisions at LHC energies
- Evidence of charge separation consistent with parity violation signals
- Enhanced sensitivity to event-by-event fluctuations in charge distribution

## Abstract

Relativistic heavy-ion collisions provide a unique opportunity to search for parity violation in non-central collisions. This could lead to charge separation perpendicular to the reaction plane. An event-by-event measurement of charge separation effect in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV using Sliding Dumbbell Method (SDM) is discussed in this article.
