\(\ttbar\) \(\afb\) Tevatron Combination

Abstract
We present the combined results on inclusive forward-backward asymmetries in the production of top-antitop quark pairs and in their decay leptons. The analysis is based on measurements by the CDF and D0 experiments at the Fermilab \(\ppbar\) Tevatron collider using the full data sets collected at \(\sqrt s =1.96\) TeV. The measured asymmetries are in agreement with the standard model predictions.
