We present the colourful antenna subtraction method, a reformulation of the antenna subtraction scheme for next-to-next-to-leading order (NNLO) calculations in QCD. The aim of this new approach is to achieve a general and process-independent construc... Read More about Automation of antenna subtraction in colour space: gluonic processes.

We describe the details of the calculation of the full colour NNLO QCD corrections to jet production observables at the LHC with antenna subtraction. All relevant matrix elements for the process pp → jj at NNLO in full colour are colour-decomposed an... Read More about Antenna subtraction for jet production observables in full colour at NNLO.

Decomposition of triple collinear splitting functions (2022)
Journal Article
Braun-White, O., & Glover, N. (2022). Decomposition of triple collinear splitting functions. Journal of High Energy Physics, 2022(9), Article 59. https://doi.org/10.1007/jhep09%282022%29059

In the kinematic region where three particles i, j, k are collinear, the multi-parton scattering amplitudes factorise into a product of a triple collinear splitting function and a multi-parton scattering amplitude with two fewer particles. These trip... Read More about Decomposition of triple collinear splitting functions.

NNLO QCD corrections in full colour for jet production observables at the LHC (2022)
Journal Article

Calculations for processes involving a high multiplicity of coloured particles often employ a leading colour approximation, where only the leading terms in the expansion of the number of colours Nc and the number of flavours nf are retained. This app... Read More about NNLO QCD corrections in full colour for jet production observables at the LHC.

Single photon production at hadron colliders at NNLO QCD with realistic photon isolation (2022)
Journal Article

Isolated photons at hadron colliders are defined by permitting only a limited amount of hadronic energy inside a fixed-size cone around the candidate photon direction. This isolation criterion admits contributions from collinear photon radiation off... Read More about Single photon production at hadron colliders at NNLO QCD with realistic photon isolation.

The Drell-Yan process at hadron colliders is a fundamental benchmark for the study of strong interactions and the extraction of electroweak parameters. The outstanding precision of the LHC demands very accurate theoretical predictions with a full acc... Read More about Third-Order Fiducial Predictions for Drell-Yan Production at the LHC.

Transverse momentum distributions in low-mass Drell-Yan lepton pair production at NNLO QCD (2022)

The production of lepton pairs at low invariant mass and finite transverse momentum resolves QCD dynamics at the boundary between the perturbative and non-perturbative domains.

The rare three-body decay of a Higgs boson to a lepton-antilepton pair and a photon is starting to become experimentally accessible at the LHC.
