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.
