Full off-shell NLO QCD predictions for ttbb at the LHC
Abstract
We report on state-of-the-art theoretical predictions for pp ttbb including full off-shell effects in the di-lepton decay channel at NLO QCD accuracy. We briefly discuss the impact of NLO QCD corrections on differential distributions and also asses theoretical uncertainties from scale and PDF dependence. Furthermore, we propose a simple kinematic reconstruction in order to distinguish b jets originating from top-quark decays from arising from gluon splittings.
