摘要

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 top-quark mass effects and the resummation of large logarithms of the zero-jettiness T 0 \( {\mathcal{T}}_0 \) , up to NNLL′ accuracy. This work extends our previous study, which was performed in the mt → ∞ 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 mt → ∞ previous implementation.
