abstract

We present the two-loop virtual corrections to Standard Model Higgs boson pair production via gluon fusion $gg\to HH$ in the heavy top quark limit. Based on this result, we evaluate the corresponding cross section at the LHC at 14 TeV in the next-to-next-to-leading order soft-virtual approximation. We find an inclusive K-factor of about 2.4, resulting in an increase close to 23% with respect to the previous available calculation at next-to-leading order. As expected, we observe a considerable reduction in the renormalization and factorization scale dependence.

  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. 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.

  3. Three-loop form factors for Higgs boson pair production in the large top mass limit

    hep-ph 2019-09 accept novelty 6.0 of 10

    New 1/m_t^2 expansion terms, up to 1/m_t^8 for the box form factors and 1/m_t^14 for the triangle form factor, are computed for the three-loop gg to HH amplitude.

  4. Exploring anomalous couplings in Higgs boson pair production through shape analysis

    hep-ph 2019-08 conditional novelty 6.0 of 10

    Anomalous Higgs couplings change the shape of the di-Higgs mass distribution, and an unsupervised clustering algorithm captures those shape differences more finely than a hand-defined taxonomy.

  5. 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.

  6. Deep Learning to Improve the Sensitivity of Higgs Pair Searches in the $4b$ Channel at the LHC

    hep-ph 2025-05 conditional novelty 5.0 of 10

    An attention-based full-event classifier constrains the Higgs self-coupling to (-0.53, 6.01) at 68% CL in the HH to 4b channel, a projected improvement over cut-based analyses.

  7. Triple Higgs Boson Production with Two Heavy Scalars at the LHC via a Simplified Approach

    hep-ph 2025-01 conditional novelty 5.0 of 10

    Double-resonant triple Higgs boson production at the LHC can be described by a single rescaling factor rho2, and projected 95% CL limits on rho2 over the (m2,m3) plane make the analysis applicable to any two-narrow-sc...
