We consider QCD radiative corrections to Higgs boson pair production through gluon fusion in proton collisions. We combine the exact next-to-leading order (NLO) contribution, which features two-loop virtual amplitudes with the full dependence on the top quark mass M t , with the next-to-next-to-leading order (NNLO) corrections computed in the large-M t approximation. The latter are improved with different reweighting techniques in order to account for finite-M t effects beyond NLO. Our reference NNLO result is obtained by combining one-loop double-real corrections with full M t dependence with suitably reweighted real-virtual and double-virtual contributions evaluated in the large-M t approximation. We present predictions for inclusive cross sections in pp collisions at √ s = 13, 14, 27 and 100 TeV and we discuss their uncertainties due to missing M t effects. Our approximated NNLO corrections increase the NLO result by an amount ranging from +12% at √ s = 13 TeV to +7% at √ s = 100 TeV, and the residual uncertainty of the inclusive cross section from missing M t effects is estimated to be at the few percent level. Our calculation is fully differential in the Higgs boson pair and the associated jet activity: we also present predictions for various differential distributions at √ s = 14 and 100 TeV, and discuss the size of the missing M t effects, which can be larger, especially in the tails of certain observables. Our results represent the most advanced perturbative prediction available to date for this process.

“…For instance, the understanding of the behaviour of the gg → HH amplitude near the top-pair production threshold has recently been used [20] to reconstruct the top-quark mass dependence of the two-loop amplitude [21,22] with high accuracy and the approach used there can also be applied at higher orders and for similar processes.…”

The top-quark mass can be determined with very high precision from a scan of the total e + e − → bbW + W − X cross section near the top-pair production threshold. We present the full calculation of electroweak and non-resonant corrections to this process at NNLO. We discuss the size of the new contributions and estimate the theory uncertainty on the top-quark mass in the PS mass scheme.13th International Symposium on Radiative Corrections (Applications of Quantum Field Theory to Phenomenology)
