abstract
We calculate the next-to-next-to-next-to-leading-order (N$^3$LO) QCD corrections to inclusive vector-boson fusion (VBF) Higgs production at proton colliders, in the limit in which there is no colour exchange between the hadronic systems associated with the two colliding protons. We also provide differential cross sections for the Higgs transverse momentum and rapidity distributions. We find that the corrections are at the 1-2 permille level, well within the scale-uncertainty of the next-to-next-to-leading-order (NNLO) calculation. The associated scale-uncertainty of the N$^3$LO calculation is typically found to be below the 2 permille level. We also consider theoretical uncertainties due to missing higher order parton distribution functions, and provide an estimate of their importance.

The paper provides the complete three-loop singular subtraction terms for qT and 0-jettiness and derives the first threshold predictions for the three-loop beam-function coefficients, later confirmed by direct calculation.
Two-loop leading-color helicity amplitudes for H+2 jets in the heavy-top limit are computed analytically and validated, enabling NNLO phenomenology and revealing an anomalous threshold.
This paper reports the first direct fully differential N3LO QCD calculation of two-jet production in e+e- annihilation, using new antenna subtraction counterterms for triple-unresolved radiation.
N³LO QCD predictions for photon-pair production are presented, demonstrating perturbative convergence.
A canonical epsilon-factorised basis, expressible entirely in dlog form despite nested square roots, is derived and numerically evaluated for the two-loop penta-box and hexa-box integral families of VBF Higgs production.
One-loop QCD helicity amplitudes for vector-boson-fusion Higgs production are derived to O(epsilon^2), with three gamma5 schemes agreeing at O(epsilon^0).
New and extended Monte Carlo tools for vector-boson-fusion double-Higgs production now support anomalous Higgs couplings, and show that NLO-plus-shower predictions approximate NNLO results while non-factorizable QCD corrections respond strongly to those couplings.
Two-loop QCD corrections to H → b b-bar g amplitude computed at higher orders in ε via Lorentz projection.
In 138 fb^-1 of 13 TeV proton collisions, CMS measures the boosted VH, H->bb signal strength as mu=0.72^{+0.75}_{-0.71}, consistent with the Standard Model.
Parton-shower matching recovers most of the large fixed-order QCD corrections in WBF Higgs production with H to b bbar decays under stringent fiducial cuts.
