摘要
We compute the contribution of order alpha(2)(S)alpha(2) 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 alpha(3)(S)alpha, and with the two dominant lowest-order ones, alpha(2)(S)alpha and alpha(S)alpha(2), to obtain phenomenological results relevant to a 8, 13, and 100TeV pp collider.
