Combined Forward-Backward Asymmetry Measurements in Top-Antitop Quark Production at the Tevatron

Abstract

The CDF and D0 experiments at the Fermilab Tevatron have measured the asymmetry between yields of forward- and backward-produced top and antitop quarks based on their rapidity difference and the asymmetry between their decay leptons. These measurements use the full data sets collected in protonantiproton collisions at a center-of-mass energy of sqrt(s)=1.96 TeV.
