We obtain the two-loop QCD amplitudes for Higgs plus three gluons including effective dimension-seven operators. This provides the S-matrix elements for the top mass corrections for Higgs plus a jet production at LHC. The results take remarkably simple analytic form. In particular, the maximally transcendental parts are identical to the corresponding results in N=4 super-Yang-Mills theory. The parts of lower transcendentality turn out to be also largely determined by the N=4 results. In this talk, we will introduce related background and also explain the new method used to obtain the results.
