NNLO+PS Double Higgs boson production with top-quark mass corrections in GENEVA
abstract
We present the implementation of the NNLO QCD corrections to double Higgs boson production at hadron colliders in GENEVA, matched to the parton shower. We include all the known top-quark mass effects and the resummation of large logarithms of the zero-jettiness $\mathcal{T}_0$, up to NNLL$^\prime$ accuracy. This work extends our previous study, which was performed in the $m_t\to \infty$ infinite top-quark mass approximation, providing a more realistic simulation framework for Higgs boson pair production. We validate our approach against NNLO predictions by MATRIX and assess the importance of mass effects comparing with our $m_t\to \infty$ previous implementation.

Fully differential Higgs boson pair production at N$^3$LO with top quark mass effects
First fully differential N3LO QCD predictions for gg->hh in the heavy-top limit, with NLO top-mass effects added; heavy-top scale uncertainty shrinks about 3x, to roughly 1-3%.
