Fully Differential VectorBosonFusion Higgs Production at NexttoNexttoLeading Order
Abstract
We calculate the fully differential nexttonexttoleadingorder (NNLO) corrections to vectorboson fusion (VBF) Higgs boson production at proton colliders, in the limit in which there is no cross talk between the hadronic systems associated with the two protons. We achieve this using a new "projectiontoBorn" method that combines an inclusive NNLO calculation in the structurefunction approach and a suitably factorized nexttoleadingorder VBF Higgs plus threejet calculation, using appropriate Higgs plus twoparton counterevents. An earlier calculation of the fully inclusive cross section had found small NNLO corrections, at the 1% level. In contrast, the cross section after typical experimental VBF cuts receives NNLO contributions of about (56)%, while differential distributions show corrections of up to (1012)% for some standard observables. The corrections are often outside the nexttoleadingorder scaleuncertainty band.
