Abstract

We compute the contribution of order α_S²α² to the cross section of a top-antitop pair in association with at least one heavy Standard Model boson -- Z, W^±, and Higgs -- by including all effects of QCD, QED, and weak origin and by working in the automated MadGraph5_aMC@NLO framework. This next-to-leading order contribution is then combined with that of order α_S³α, and with the two dominant lowest-order ones, α_S²α and α_Sα², to obtain phenomenological results relevant to a 8, 13, and 100~TeV pp collider.
