摘要
We present the results for the associated production of Higgs boson with vector boson computed at threshold (NLO)-L-3 in QCD. We use the recently available result of the threshold contributions to the inclusive Drell-Yan production cross-section at third order in the strong coupling constant. We have implemented it in the publicly available computer package vh@nnlo, thereby obtaining the numerical impact of threshold (NLO)-L-3 contributions for the first time. We find that the inclusion of such corrections do reduce theoretical uncertainties resulting from the renormalization scale.
