- Terence Wyatt: Wyatt supervised a postdoctoral researcher and PhD student who made important contributions to the research in this paper. They proposed, designed, implemented and commissioned a multivariate discriminant (BDT) to veto non-prompt leptons that arise from the dominant backgrounds in the multilepton search channels. This discriminant was used to select events in sections 5.A and 5.B. The discriminant increased the analysis sensitivity in the multilepton final state, ultimately allowing evidence for ttH production to be claimed (the main results of the paper). The PhD student estimated the backgrounds from non-prompt leptons in one of the search channels (section VI.B.1).
