Abstract
We discuss nonfactorizable QCD corrections to Higgs boson production in vector boson fusion at the Large Hadron Collider. We point out that these corrections can be computed in the eikonal approximation retaining all the terms that are not suppressed by the ratio of the transverse momenta of the tagging jets to the total center-of-mass energy. Our analysis shows that in certain kinematic distributions the nonfactorizable corrections can be as large as a percent making them quite comparable to their factorizable counterparts.

Current understanding of QCD corrections to the VBF Higgs boson production is highly advanced: following the original calculation of the next-to-leading (NLO) corrections [3], both the next-to-next-to-leading (NNLO) [4,5,6] and the next-to-next-to-next-to-leading (N3LO) [7] corrections were computed in the so-called structure function approximation [8]
Summary
Vector boson fusion (VBF) is one of the two key channels for Higgs boson production at the Large Hadron Collider (LHC) [1,2]. We discuss nonfactorizable QCD corrections to Higgs boson production in vector boson fusion at the Large Hadron Collider. We point out that these corrections can be computed in the eikonal approximation retaining all the terms that are not suppressed by the ratio of the transverse momenta of the tagging jets to the total center-of-mass energy.
