I apply FDR—a recently introduced fourdimensional approach to quantum field theories (QFTs)— to the computation of the NLO QCD corrections to H → gg in the large top mass limit. The calculation involves all key ingredients of QCD—namely ultraviolet, infrared, and collinear divergences, besides αS renormalization—and paves the way for successful use of FDR in massless oneloop QFT computations.

Complete three - loop QCD corrections to the decay H → γγ

We present the result for the three-loop singlet QCD corrections to the decay of a Higgs boson into two photons and improve the calculation for the non-singlet case. With the new result presented, the decay width Γ(H → γγ) is completely known at O(GFααs, GFα).

Virtual corrections to gg → H to two loops in the heavy top limit

The virtual corrections to the production cross section of a Standard Model Higgs boson are computed up to order α s . Using an effective Lagrangian for the limit Mt → ∞, we evaluate the relevant massless two-loop vertex diagrams by mapping them onto three-loop two-point functions, following a method recently introduced by Baikov and Smirnov [1]. As a result, we find a gauge-invariant contribut...

NNLO Computational Techniques : the Cases H → γγ and H → gg ‡ ‡

A large set of techniques needed to compute decay rates at the two-loop level are derived and systematized. The main emphasis of the paper is on the two Standard Model decays H → γγ and H → gg. The techniques, however, have a much wider range of application: they give practical examples of general rules for two-loop renormalization; they introduce simple recipes for handling internal unstable p...
