Contribution

It provides a comprehensive overview of the current theoretical status and explores novel observables for future top-quark charge asymmetry studies at the LHC.

Findings

Standard Model predictions for charge asymmetry at Tevatron and LHC

Possible explanations of Tevatron excess via new physics

Proposals for novel observables at the LHC

Abstract

I review the current status of the charge asymmetry in hadronic top-quark pair production from a theory perspective. The standard-model predictions for the observables at the Tevatron and LHC are being discussed, as well as possible explanations of the Tevatron excess in terms of new physics. I give an outlook for future investigations of the top-quark charge asymmetry, focussing on novel observables at the LHC.
