摘要：We discuss the production of top–anti-top quark pairs in association with a hard jet at the Tevatron
and at the LHC and we report on the calculation of the next-to-leading order QCD corrections to
this process. Numerical results for the t¯t+jet cross section and the forward–backward charge
asymmetry are presented. The corrections stabilize the leading-order prediction for the cross
section. In contrast, the charge asymmetry receives large corrections. The dependence of the
cross section as well as the asymmetry on the minimum transverse momenta used to define the
additional jet is studied in detail for the Tevatron.
