NNLO corrections to VBF Higgs boson production

TL;DR

This paper presents the calculation of NNLO QCD corrections to Higgs production via vector boson fusion, showing corrections are small and weakly dependent on kinematic variables, enhancing precision in theoretical predictions.

Contribution

It provides a fully differential NNLO calculation for VBF Higgs production, implemented in the NNLOJET framework, with detailed analysis of correction magnitudes and kinematic dependence.

Findings

NNLO corrections are about ±5% in magnitude.

Corrections show weak dependence on jet kinematics.

Results improve theoretical precision for VBF Higgs production.

Abstract

This talk expands on recently published results for the factorising next-to-next-to-leading order (NNLO) QCD corrections to Higgs boson production in the vector boson fusion (VBF) channel. The calculation is fully differential in the kinematics of the Higgs boson and the final state jets and is implemented in the NNLOJET framework for computing higher-order QCD corrections. We find the NNLO corrections to be limited in magnitude to about $\pm 5$\% with a weak kinematical dependence in the transverse momenta and rapidity separation of the two tagging jets.
