Higgs-boson pair production at hadron colliders is dominantly mediated by
the loop-induced gluon-fusion process gg→HH that is generated by heavy
top loops within the Standard Model with a minor per-cent level
contamination of bottom-loop contributions. The QCD corrections turn out
to be large for this process. In this talk, we discuss the
top-Yukawa-induced part of the electroweak corrections to this process and
their relation to an effective trilinear Higgs coupling with integrated
out top-quark contributions.
