Summary
The calculation of Higgs boson pair production in gluon fusion at next-to-leading order in the strong coupling constant with full top-quark mass dependence is presented. The usage of the programs GoSam, Reduze and SecDec for the computation and numerical evaluation of the most complicated piece, the virtual two-loop amplitude, is
explained. The cross section and invariant mass distribution are shown, in addition to a comparison with various approximations proposed in the literature.
