Abstract Top quark mass suppressed terms are calculated for the virtual amplitude for Higgs production in gluon fusion at three-loop level, i.e. O ( α s 3 ) . The method of asymptotic expansions in its automated form is used to evaluate the first three non-vanishing orders in terms of M H 2 / M t 2 , where the first order corresponds to the known results of the effective Lagrangian approach.
