Top-Yukawa-induced corrections to Higgs pair production
Margarete Mühlleitner, Johannes Schlenk, Michael Spira
Abstract
A bstract 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 note, we derive the top-Yukawa-induced part of the electroweak corrections to this process and discuss their relation to an effective trilinear Higgs coupling with integrated out top-quark contributions.
