Abstract

We compute the next-to-next-to-leading order QCD corrections to Higgs boson production in weak boson fusion followed by its decay to a b overline{b} pair or to a pair of leptonically-decaying W bosons. Our calculation allows us to compute realistic fiducial cross sections and assess the impact of fiducial cuts applied to the Higgs boson decay products on the magnitude of QCD radiative corrections in weak boson fusion.

Highlights

JHEP02(2022)046 in this channel relative to the Standard Model expectations
We turn to Higgs production in weak boson fusion followed by the Higgs decay to two W bosons which decay leptonically, H → W W ∗ → eνeμνμ
We presented a computation of next-to-next-to-leading order (NNLO) QCD corrections to Higgs boson production in weak boson fusion using the nested soft-collinear subtraction scheme

Summary

Introduction

JHEP02(2022)046 in this channel relative to the Standard Model expectations. These studies are supported by the development of sophisticated theoretical tools that allow accurate descriptions of Higgs boson production in WBF.1. We summarize the technical aspects of the calculation including a brief discussion of the nested soft-collinear subtraction scheme [43] and an explanation of how we apply it to the computation of factorizable NNLO QCD corrections to Higgs boson We present the fiducial cross sections for the production of a stable Higgs boson in WBF at NNLO in QCD.
