We present the next-to-leading order QCD corrections to Higgs boson pair production in vector boson fusion, including the leading operators in the framework of Higgs Effective Field Theory (HEFT). The corresponding calculation is based on an automated interface between the Monte Carlo event generator Whizard and the one-loop amplitude generator GoSam. The QCD corrections also include non-factorising diagrams and diagrams of Higgs-Strahlung type, thus going beyond the structure function approach. We find that some constellations of anomalous couplings, while being well within the current experimental constraints, can have a significant impact on the shape of typical observables for this process.

  1. A HEFT Perspective on the Type-II Seesaw Model and the Complete Basis of Lepton-Number-Violating Operators

    hep-ph 2026-07 accept novelty 8.0 of 10

    First complete tree-level HEFT matching of the type-II seesaw and a Hilbert-series-checked, flavor-complete basis of lepton-number-violating HEFT operators through O(p^4).

  2. Precise predictions for double Higgs production in association with a vector boson in Effective Field Theory

    hep-ph 2026-07 conditional novelty 6.0 of 10

    First NNLO QCD cross sections for pp→Vhh in SMEFT and HEFT, provided as interpolated coefficients; W±hh K-factors are almost EFT-independent while Zhh is sensitive to gluon-initiated contributions.

  3. Anomalous Couplings from the Electroweak Chiral Lagrangian for Off-Shell Higgs in $gg\to Z_L Z_L$

    hep-ph 2025-07 accept novelty 6.0 of 10

    In the electroweak chiral Lagrangian, off-shell Higgs contributions to gg to Z_L Z_L at leading order reduce to two independent combinations of the anomalous couplings c_t, c_V, and c_ggh.

  4. One-Loop Calculations in Effective Field Theories with GoSam-3.0

    hep-ph 2025-07 accept novelty 6.0 of 10

    GoSam-3.0 extends automated one-loop amplitude generation to SMEFT and HEFT with flexible truncation orders, loop-suppression counting, and improved speed and stability.

  5. Harnessing Higgs Kinematics for HEFT Constraints

    hep-ph 2025-06 conditional novelty 4.0 of 10

    Reweighting Standard Model di-Higgs events with a momentum-dependent HEFT coupling gives expected Run 3 and HL-LHC constraints on a_22 and a_dd2, with four-top data helping to pin down a_22.
