description This note presents Monte Carlo generator comparisons of the ttbb and ttW processes at particle level. The aim is to compare the modelling of important backgrounds to ttH measurements in the Higgs to bbbar and Higgs to multi-lepton decay channels and the treatment of the associated theory uncertainties for a combination of the full Run-2 ttH results from ATLAS. As a first step, modelling and theory uncertainties as used in ATLAS are compared in the relevant analysis regions.
