Description

I will present fully differential NNLO corrections to vector-boson fusion (VBF) Higgs production at hadron colliders, in the limit in which there is no cross-talk between the hadronic systems associated with the two protons.The result is obtained by combining an inclusive NNLO calculation in the structure-function approach and a suitably factorised NLO VBF Higgs plus 3-jet calculation, supplemented with appropriate Higgs plus 2-parton counter-events. An earlier calculation of the fully inclusive cross section had found small NNLO corrections, at the percent level. In contrast, I will show that the cross section after typical experimental VBF cuts and differential distributions receive larger NNLO corrections.
