# Two-loop massless QCD corrections to the $g + g \to H + H$ four-point amplitude

Banerjee, Pulak; Borowka, Sophia; Dhani, Prasanna K; Gehrmann, Thomas; Ravindran, V (2018). Two-loop massless QCD corrections to the $g + g \to H + H$ four-point amplitude. Journal of High Energy Physics, 2018(11):130.

## Abstract

We compute the two-loop massless QCD corrections to the four-point amplitude g + g → H + H resulting from effective operator insertions that describe the interaction of a Higgs boson with gluons in the infinite top quark mass limit. This amplitude is an essential ingredient to the third-order QCD corrections to Higgs boson pair production. We have implemented our results in a numerical code that can be used for further phenomenological studies.
