Description

Gluon fusion is the main mechanism for Higgs production at the LHC. The perturbative behaviour of the cross-section poses great challenges for modern calculational methods, since it requires the NNLO QCD corrections to be taken into account. In this talk, I will describe a simple new method for perturbative computations of fully differential quantities beyond NLO. I will show results for various kinematic distributions of the Higgs boson in NNLO QCD and the accepted diphoton-signal cross-section after all standard CMS and ATLAS proposed cuts are applied. Finally, I will present distributions for the diphoton signal with good discriminating properties from the background.
