Description
The leading and next-to-leading order QCD predictions for Higgs boson pair production at hadron colliders suffer from a large mass renormalisation scheme uncertainty related to the choice of the top quark mass. In this talk, I will discuss how the Method of Regions and factorisation in SCET can be utilised to understand the dependence of the result on the value of the intermediate quark mass and gain control over the sizeable logarithmic mass corrections in the $gg \to HH$ amplitudes at leading and next-to-leading powers in the high-energy limit.
