abstract

In this work we analyse the triple Higgs boson production cross section at hadron colliders via gluon fusion, and present for the first time the full set of QCD NNLO corrections in the heavy top limit. In order to account for finite top mass effects we perform two different reweighting procedures, and study the dependence of the result on the choice of the approximation. Combining the most accurate predictions available to date, we present the following result for the total NNLO cross section for triple Higgs boson production at a 100 TeV collider: $\sigma_\text{NNLO}=5.56^{+5\%}_{-6\%} \pm 20\%$ fb, where the first uncertainty is an estimate for higher order effects from scale variations, while the last one is an estimate for the missing finite top mass effects.

  1. An analytic result for the $0 \to ggHHH$ amplitude

    hep-ph 2025-07 conditional novelty 7.0 of 10

    The authors present the complete leading-order one-loop amplitude for gg to HHH in closed analytic form, with full top and bottom quark mass dependence, validated against two independent numerical programs.

  2. 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).

  3. 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...
