This analysis implements NNLO QCD corrections for double higgs boson production, including top-quark mass effects and large logarithm resummation.
A bstract We present the implementation of the NNLO QCD corrections to double Higgs boson production at hadron colliders in G eneva , matched to the parton shower. We include top-quark mass effects and the resummation of large logarithms of the zero-jettiness T₀ T 0 , up to NNLL ′ accuracy. This work extends our previous study, which was performed in the m t → ∞ infinite top-quark mass approximation, providing a more realistic simulation framework for Higgs boson pair production. We validate our approach against NNLO predictions by M atrix and assess the importance of mass effects comparing with our m t → ∞ previous implementation.
