Abstract
We present a measurement of the forward--backward asymmetry in top quark--antiquark production using the full Tevatron Run II data set collected by the D0 experiment at Fermilab. The measurement is performed in $\text{lepton}+\mathrm{jets}$ final states using a new kinematic fitting algorithm for events with four or more jets and a new partial reconstruction algorithm for events with only three jets. Corrected for detector acceptance and resolution effects, the asymmetry is evaluated to be ${A}_{\mathrm{FB}}=(10.6\ifmmode\pm\else\textpm\fi{}3.0)%$. Results are consistent with the standard model predictions which range from 5.0% to 8.8%. We also present the dependence of the asymmetry on the invariant mass of the top quark--antiquark system and the difference in rapidities of the top quark and antiquark.
