Constraining the Higgs boson self-interaction is one of the main goals for the high luminosity
phase of the LHC. A promising channel to this aim is the simultaneous production of two Higgs
bosons from gluon fusion. For the interpretation of the data, precise theoretical predictions, also
for differential cross sections, are needed. Following current projections this requires electroweak
corrections at next-to-leading order. We present the contributions of top-Yukawa and Higgs self-
interaction-type, as well as the first steps towards inclusion of the complete NLO electroweak
corrections.
