Description

In this talk, I will present the first analytical calculations of leading two-loop Yukawa corrections to the Higgs pair production in the high energy limit. The electroweak corrections are expected to have a percent-level impact on the cross sections, and hence it is desirable to have the amplitudes ready for the future phenomenological studies. As a first step in this direction, we compute the leading two-loop Yukawa corrections of gg->HH process originating from exchanging an additional Higgs boson between virtual top-quark lines. In particular, I will discuss new theoretical advances which enable the analytical calculations.
