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...

Event generators for high-energy physics experiments (2024)
Journal Article
Campbell, J. M., Diefenthaler, M., Hobbs, T. J., Höche, S., Isaacson, J., Kling, F., Mrenna, S., Reuter, J., Alioli, S., Andersen, J. R., Andreopoulos, C., Ankowski, A. M., Aschenauer, E.

SciPost Physics, 16(5), Article 130. https://doi.org/10.21468/scipostphys.16.5.130

We provide an overview of the status of Monte-Carlo event generators for high-energy particle physics. Guided by the experimental needs and requirements, we highlight areas of active development, and opportunities for future improvements. Particular...

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...
