Description
In this talk, I will present a first look at the two-loop electroweak
corrections to Higgs boson pair production in gluon-fusion, which
might have a sizeable impact on the cross section. We have performed an
analytic calculation of the two-loop diagrams contributing
to gg->HH where a virtual Higgs boson is exchanged in the top quark loop.
I will briefly describe our method used to solve massive two-loop box
integrals and then discuss results for the form factors. We show that
precise results can be obtained, even for $p_t \approx 100$ GeV and above.
