Electroweak corrections to Higgs boson pair production: the top-Yukawa and self-coupling contributions (2024)
Journal Article
Heinrich, G., Jones, S. P., Kerner, M., Stone, T. W., & Vestner, A. (2024). Electroweak corrections to Higgs boson pair production: the top-Yukawa and self-coupling contributions. Journal of High Energy Physics, 2024(11), Article 40. https://doi.org/10.1007/jhep11%282024%29040

We present results for the Yukawa-enhanced and Higgs self-coupling type electroweak corrections to di-Higgs production in gluon fusion. The calculation of the corresponding four-scale, two-loop amplitude is carried out retaining the exact symbolic de...

Dissecting polytopes: Landau singularities and asymptotic expansions in 2 → 2 scattering (2024)
Journal Article
Gardi, E., Herzog, F., Jones, S., & Ma, Y. (2024). Dissecting polytopes: Landau singularities and asymptotic expansions in 2 → 2 scattering. Journal of High Energy Physics, 2024(8), Article 127. https://doi.org/10.1007/jhep08%282024%29127

Parametric representations of Feynman integrals have a key property: many, frequently all, of the Landau singularities appear as endpoint divergences. This leads to a geometric interpretation of the singularities as faces of Newton polytopes, which f...

Two-loop amplitudes for t t ¯ H production: the quark-initiated N f -part (2024)
Journal Article
Agarwal, B., Heinrich, G., Jones, S. P., Kerner, M., Klein, S. Y., Lang, J., …Olsson, A. (2024). Two-loop amplitudes for t t ¯ H production: the quark-initiated N f -part. Journal of High Energy Physics, 2024(5), Article 13. https://doi.org/10.1007/jhep05%282024%29013

We present numerical results for the two-loop virtual amplitude entering the NNLO corrections to Higgs boson production in association with a top quark pair at the LHC, focusing, as a proof of concept of our method, on the part of the quark-initiated...
