In this note we discuss the combination of the usual renormalization and factorization scale uncertainties of Higgs-pair production via gluon fusion with the novel uncertainties originating from the scheme and scale choice of the virtual top mass. Moreover, we address the uncertainties related to the top-mass definition for different values of the trilinear Higgs coupling and their combination with the other uncertainties.

  1. Fully differential Higgs boson pair production at N$^3$LO with top quark mass effects

    hep-ph 2026-01 conditional novelty 7.0 of 10

    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%.

  2. The structure of quark mass corrections in the $gg \rightarrow HH$ amplitude at high-energy

    hep-ph 2024-12 conditional novelty 7.0 of 10

    The leading-power mass logarithms in high-energy gg to HH are shown to originate solely from top-quark mass renormalization, enabling a resummation that sharply reduces the mass-scheme uncertainty of the virtual amplitude.

  3. Combination of Higgs boson measurements at $\sqrt{s} =$ 13 TeV and their interpretations by the ATLAS experiment

    hep-ex 2026-08 accept novelty 6.0 of 10

    The combined ATLAS Higgs measurements agree with the Standard Model and yield a self-coupling modifier kappa_lambda = 1.3 (+3.1/-1.6), a total width of 3.6 (+2.1/-1.6) MeV, and a b-quark running mass of 2.73 (+0.27/-0...

  4. HiggsTools for LHC Run 3 and Beyond

    hep-ph 2026-08 conditional novelty 6.0 of 10

    The HiggsTools toolbox is upgraded for LHC Run 3 with 13.6 and 14 TeV cross-sections, resonant and non-resonant di-Higgs predictions including interference, and a recast four-top search limit.

  5. Search for nonresonant triple Higgs boson production in the final state with six bottom quarks in proton-proton collisions at $\sqrt{s}$ = 13 TeV

    hep-ex 2026-07 accept novelty 6.0 of 10

    No excess is observed; the 95% CL upper limit on nonresonant HHH→6b is 44 fb (588×SM), with κ3 constrained to −7.4 < κ3 < 12.4 (κ4=1) and κ4 to −177 < κ4 < 185 (κ3=1).

  6. Search for the nonresonant and resonant production of a Higgs boson in association with an additional scalar boson in the $\gamma\gamma\tau\tau$ final state in proton-proton collisions at $\sqrt{s}$ = 13 TeV

    hep-ex 2025-06 accept novelty 6.0 of 10

    CMS finds no evidence for Higgs-pair or new-scalar production in the two-photon plus two-tau final state and sets new upper limits on these processes.

  7. Probing new physics in the Boosted $HH \to b\bar{b}\gamma\gamma$ channel at the LHC

    hep-ph 2025-12 conditional novelty 5.0 of 10

    A dedicated boosted-jet category in HH→bbγγ is projected to narrow the κ2V constraint to [-0.4, 2.6] at 95% CL and improve heavy-resonance limits by 1–2x at 308 fb⁻¹.

  8. Deconstructing resonant Higgs pair production at the LHC: effects of coloured and neutral scalars in the NMSSM test case

    hep-ph 2025-06 conditional novelty 5.0 of 10

    In the NMSSM, interference between heavy Higgs resonances, SM top loops and stop loops can strongly distort the di-Higgs invariant mass spectrum, and a diagram-by-diagram decomposition makes these distortions interpretable.

  9. Sensitivity to Triple Higgs Couplings via Di-Higgs Production in the RxSM at the (HL-)LHC and future $e^+e^-$ Colliders

    hep-ph 2025-02 conditional novelty 5.0 of 10

    In the real singlet extension of the Standard Model, the di-Higgs mass spectrum at the HL-LHC and at ILC1000 carries a measurable imprint of the triple Higgs coupling λhhH, and the pure-resonant approximation used by ...

  10. Improved analysis of non-resonant Higgs boson pair production in the $b\bar{b}\tau^+\tau^-$ final state with $196$ fb$^{-1}$ of data collected at $\sqrt{s}$ = 13 TeV and 13.6 TeV with the ATLAS detector

    hep-ex 2026-07 accept novelty 4.5 of 10

    ATLAS finds μ_HH = 2.6^{+1.4}_{-1.0} in bbττ with Run 2+3 data, 2.6σ over background-only, and first 3.5σ evidence for ZH in this final state.

  11. {\tt ggxy}: a flexible library to compute gluon-induced cross sections

    hep-ph 2025-06 accept novelty 4.0 of 10

    A new software library, ggxy, computes NLO QCD cross sections for gg to HH and reproduces previous exact results with much shorter runtimes.

  12. Interference effects in new physics searches

    hep-ph 2026-01 accept novelty 3.0 of 10

    Interference between new-physics resonances and Standard Model backgrounds must be included in collider searches; the review shows it can distort, enhance, or even cancel expected signals.
