NNLO Higgs production beyond heavy top limit at LHC

We present the NNLO cross section for the Standard Model Higgs boson production at the CERN Large Hadron Collider (LHC) including finite top quark mass effects. Our calculation is based on the evaluation of the imaginary part of the forward scattering amplitudes which, via the optical theorem, directly leads to the total cross section. We apply the asymptotic expansion in order to obtain correction terms suppressed by the heavy top quark mass. This corrections to the hadronic cross sections are found to be small compared to the scale uncertainty, thus justifying the use of heavy top quark approximation in many published results.
