Top mass effects in Higgs production at next-to-next-to-leading order QCD: virtual corrections

Harlander, Robert V., Ozeren, Kemal J.

Understand

Top quark mass suppressed terms are calculated for the virtual amplitude for Higgs production in gluon fusion at three-loop level, i.e.

  • O(\alpha_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.
