Next-to-Leading Order QCD Corrections to t\overline t b\overline b Production at the LHC

M. Worek

In this contribution, we summarize the results from an NLO computation of the production of t\bar t b\bar b in hadronic collisions. The results are obtained by combining two programs: Helac-1Loop, based on the OPP method and the reduction code CutTools, for the virtual one-loop matrix elements and Helac-Dipoles for the real-emission contributions. Selected numerical results are presented for the LHC.
