Higgs-pair production via gluon fusion: top-Yukawa-and light-quark-induced electroweak corrections

Year: 2026

Type: article

Abstract: Gluon fusion, gg → HH, is the dominant Higgs-pair production process at the Large Hadron Collider (LHC) and provides the first direct access to the trilinear Higgs self-interaction. The process is loop-induced, with the main contribution emerging from top-quark loops within the Standard Model. In the past, the QCD corrections have been calculated and found to increase the cross section significantly. With the anticipated accuracies achievable at the high-luminosity LHC (HL–LHC), the theoretical uncertainties will be of increased relevance to compete with the experimental precision at the level of less than 30%. In this work, we take the next steps towards the determination of the complete electroweak corrections at next-to-leading order by calculating the full top-Yukawa and light-quark induced corrections. These corrections modify the cross section moderately in the kinematical regimes of interest.
