We present a new Monte Carlo code for Higgs boson pair production at next-to-leading order in the POWHEG-BOX Monte Carlo approach. The code is based on analytic results for the two loop virtual corrections which include the full top quark mass dependence. This feature allows to freely assign the value of all input parameters, including the trilinear Higgs boson self coupling, as well as to vary the renormalization scheme employed for the top quark mass. We study the uncertainties due to the top-mass renormalization scheme allowing the trilinear Higgs boson self coupling to vary around its Standard Model value including parton shower effects. Results are presented for both inclusive and differential observables.

  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. 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.

  3. 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).

  4. Phenomenology of a Kinetic Higgs Portal

    hep-ph 2025-10 conditional novelty 6.0 of 10

    A momentum-dependent Higgs portal can hide invisible decays, make four-top production the most sensitive probe, and open a dark-matter region immune to direct detection.

  5. NNLO+PS Double Higgs boson production with top-quark mass corrections in GENEVA

    hep-ph 2025-07 conditional novelty 6.0 of 10

    First NNLO+parton-shower simulation of double Higgs production in GENEVA that includes approximate finite top-quark mass corrections (FTapprox), validated against MATRIX.

  6. 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.

  7. {\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.
