Higgs Production in Gluon Fusion to {O}(α 4s)
Abstract
The calculation of the NNLO QCD corrections to the partonic process gg --> H is outlined. For the coupling of the Higgs boson to the gluons we use an effective Lagrangian in the limit of a heavy top quark. The focus is on the evaluation of the virtual two-loop corrections. It is shown that the leading ole terms are in agreement with general formula by Catani.
