Journal Article
Buccioni, F., Chen, X., Feng, W. J., Gehrmann, T., Huss, A., & Marcoli, M. (2025). Precise Predictions for Event Shapes in Diphoton Production at the LHC. Physical Review Letters, 134(17), Article 171901. https://doi.org/10.1103/PhysRevLett.134.171901

Photon pair production is an important benchmark process at the LHC, entering Higgs boson studies and new physics searches. It has been measured to high accuracy, allowing for detailed studies of event shapes in diphoton final states. To enable preci...

Generalised antenna functions for higher-order calculations (2024)
Journal Article
Fox, E., Glover, N., & Marcoli, M. (2025). Generalised antenna functions for higher-order calculations. Journal of High Energy Physics, 2024(12), Article 225. https://doi.org/10.1007/jhep12%282024%29225

In this paper we discuss the definition, the construction and the implementation of generalised antenna functions for final-state radiation up to Next-to-Next-to-Leading Order (NNLO) in QCD. Generalised antenna functions encapsulate the singular beha... Read More about Generalised antenna functions for higher-order calculations.

Antenna subtraction for processes with identified particles at hadron colliders (2024)
Journal Article
Bonino, L., Gehrmann, T., Marcoli, M., Schürmann, R., & Stagnitto, G. (2024). Antenna subtraction for processes with identified particles at hadron colliders. Journal of High Energy Physics, 2024(8), Article 73. https://doi.org/10.1007/jhep08%282024%29073

Collider processes with identified hadrons in the final state are widely studied in view of determining details of the proton structure and of understanding hadronization. Their theory description requires the introduction of fragmentation functions,... Read More about Antenna subtraction for processes with identified particles at hadron colliders.

The colourful antenna subtraction method (2024)
Journal Article
Gehrmann, T., Glover, E. W. N., & Marcoli, M. (2024). The colourful antenna subtraction method. Journal of High Energy Physics, 2024(3), Article 114. https://doi.org/10.1007/jhep03%282024%29114

We present a general subtraction scheme for NNLO calculations in massless QCD: the colourful antenna subtraction method. It is a reformulation of the antenna subtraction approach designed to address some of the limitations of the traditional framewor... Read More about The colourful antenna subtraction method.

Radiation from a gluon-gluino colour-singlet dipole at N 3 LO (2023)
Journal Article
Chen, X., Jakubčík, P., Marcoli, M., & Stagnitto, G. (2023). Radiation from a gluon-gluino colour-singlet dipole at N 3 LO. Journal of High Energy Physics, 2023(12), Article 198. https://doi.org/10.1007/jhep12%282023%29198

We compute the quantum chromodynamics (QCD) corrections to the decay of a neutralino to gluinos and partons at next-to-next-to-next-to-leading order (N3LO) in the strong coupling constant αs, integrated separately over the phase-space of two, three,...
