NNLO+PS matching for gluon-fusion Higgs pair production is implemented in MiNNLOPS with approximate top-mass effects, validated against fixed-order NNLO and compared to GENEVA, with results for decay channels and trilinear coupling variations.

abstract
We consider the virtual corrections to the process $gg\to HH$ at NLO in the high energy limit and compute the corresponding planar master integrals in an expansion for small top quark mass. We provide details on the evaluation of the boundary conditions and present analytic results expressed in terms of harmonic polylogarithms.

Analytic two-loop electroweak corrections to four-point amplitudes are computed in the high-energy limit of the Standard Model, applied to Higgs pair production where logarithmic and power corrections yield sizeable effects.
