Next-To-Leading Order QCD Corrections to $pp \to \overline{t}t b\overline{b} +X$ at the LHC

We report on the calculation of the full next-to-leading order QCD corrections to the production of top anti-top bottom anti-bottom (ttbb) final states at the LHC, which deliver a serious background contribution to the production of a Higgs boson (decaying into a bottom anti-bottom pair) in associat...

description We report on the calculation of the full next-to-leading order QCD corrections to the production of top anti-top bottom anti-bottom (ttbb) final states at the LHC, which deliver a serious background contribution to the production of a Higgs boson (decaying into a bottom anti-bottom pair) in association with a top anti-top pair. While the corrections significantly reduce the unphysical scale dependence of the leading-order cross section, our results predict an enhancement of the ttbb production cross section by a K-factor of about 1.8.
