Abstract: This report describes the recent efforts to compute analytic formulae for theNext-to-Leading-Order NLO QCD corrections to Higgs plus two jet production athadron colliders. In these calculations the Higgs boson couples to gluons via atop-quark loop which is integrated out to form an effective vertex. Theamplitudes are further simplified by splitting the real Higgs scalar into thesum of two complex scalars phi and phi^dagger. Four-dimensional unitarity isused to construct the cut-containing pieces of the amplitude, while a varietyof bootstrap and Feynman diagram techniques are used to construct the rationalpieces. The results described here are valid in the limit of a large top quarkmass and when the transverse momenta of the jets are less than mt.
