Real emission corrections to Higgs production via gluon-fusion, at order αs4, lead to a Higgs plus two-jet final state. We present the calculation of these scattering amplitudes, as induced by top-quark triangle-, box- and pentagon-loop diagrams. These diagrams are evaluated analytically for arbitrary top mass mt. We study the renormalization and factorization scale-dependence of the resulting H+2 jet cross section, and discuss phenomenologically important distributions at the LHC. The gluon-fusion results are compared to expectations for weak-boson fusion cross sections.
