Theoretical uncertainties in the simulation of ttbb production represent one of the main obstacles that still hamper the observation of Higgs-boson production in association with top-quark pairs in the H->b?b. We present a next-to-leading order (NLO) simulation t?tb?b production with massive b-quarks matched to Pythia within the POWHEG method with the hope of reconciling tension between previous calculations based on
the MC@NLO method.
