Next-to-Leading-Order QCD Corrections to tt¯+jet Production at Hadron Colliders
Abstract
We report on the calculation of the next-to-leading-order QCD corrections to the production of top-quark top-antiquark pairs in association with a hard jet at the Fermilab Tevatron and the CERN Large Hadron Collider. We present results for the tt¯+jet cross section and the forward-backward charge asymmetry. The corrections stabilize the leading-order prediction for the cross section. The charge asymmetry receives large corrections.
