Description
We consider the next-to-leading order electroweak corrections to the Higgs boson pair production in gluon fusion. This requires the computation of two-loop four-point amplitudes with massive internal particles such as top quarks, Higgs and gauge bosons. We perform analytic calculations both in the high-energy and large top-quark mass limits. In particular, we show that our high energy expansion can even yield precise results above $p_t \approx 120$ GeV. The technical challenges are described and results for the form factors are presented.
