Asymmetries at the Tevatron

Abstract

In this report, we summarize the latest results of the top-quark pair production asymmetry and present the new result of bottom-quark pair production asymmetry. By looking at the results obtained by the CDF experiment, one can see a discrepancy in both tt inclusive and lepton-based measurements. The D0 results of the tt production asymmetry are compatible with the standard-model predictions as well as with the CDF results. The CDF measurement of bb production asymmetry presents consistency with both zero and with the standard-model predictions.
