The production of Higgs bosons in weak boson fusion has the second largest cross section among Higgs-production processes at the Large Hadron Collider.

Abstract

The production of Higgs bosons in weak boson fusion has the second largest cross section among Higgs-production processes at the Large Hadron Collider. As such, this process plays an important role in detailed studies of Higgs interactions with vector bosons. In this paper we extend the available description of Higgs boson production in weak boson fusion by considering anomalous weak interactions of the Higgs boson and next-to-next-to-leading order (NNLO) QCD radiative corrections at the same time. We find that, while leading order QCD predictions are too uncertain to allow for detailed studies of the anomalous couplings, next-to-leading order (NLO) QCD results are sufficiently precise, most of the time. The NNLO QCD corrections alter the NLO QCD predictions only marginally, but their availability enhances the credibility of conclusions based on NLO QCD computations.
