Perturbative QCD at NNLO and N3LO: recent progress in antenna subtraction

by Matteo Marcoli (University of Durham)

Monday 12 Jan 2026, 14:00 → 15:00 Europe/Zurich

4/3-006 - TH Conference Room (CERN)

In this talk, I will briefly review the state of the art of fixed-order calculations in QCD and present recent developments in the context of the antenna subtraction method. In particular, I will discuss progress aimed at automation and computational efficiency at NNLO, especially for high-multiplicity processes, and illustrate the definition and use of generalized antenna functions for final-state radiation, highlighting their phenomenological applications. I will also present the first N3LO differential calculation performed entirely using antenna subtraction for jet production at electron–positron colliders, and discuss how the extension of generalized antenna functions at N3LO will enable to tackle of more complex processes at this perturbative order.
