# Nonfactorizable QCD Effects in Higgs Boson Production via Vector Boson Fusion

## TL;DR

This paper investigates nonfactorizable QCD corrections in Higgs production via vector boson fusion, showing they can be significant in certain kinematic distributions and are calculable using the eikonal approximation.

## Contribution

It introduces a method to compute nonfactorizable QCD corrections in Higgs VBF production, highlighting their potential impact on precision measurements.

## Key findings

- Nonfactorizable corrections can reach about 1% in specific distributions.
- The eikonal approximation effectively captures these corrections.
- Nonfactorizable effects are comparable to factorizable ones in certain regimes.

## 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 counter-parts.
