# Top-antitop charge asymmetry measurements in the lepton+jets channel with the ATLAS detector

## TL;DR

This paper presents a measurement of the top-antitop charge asymmetry in proton-proton collisions at 8 TeV using the ATLAS detector, employing Bayesian unfolding and differential analysis to improve understanding of top quark production asymmetries.

## Contribution

First measurement of top-antitop charge asymmetry in the lepton+jets channel at 8 TeV with Bayesian unfolding and differential analysis.

## Key findings

- Differential charge asymmetry distributions provided.
- Results consistent with Standard Model predictions.

## Abstract

We report a measurement of the charge asymmetry in top quark pair production with the ATLAS experiment at the LHC using 20.3 fb$^{-1}$ of pp collision data at $\sqrt{s}$ = 8 TeV. The data are unfolded using a fully Bayesian unfolding method. Differential measurements of the charge asymmetry are performed.
