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.

Decomposition of triple collinear splitting functions (2022)
Journal Article

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.

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)

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.
