Recent progress in antenna subtraction at NNLO and N${}^3$LO

Abstract

In this contribution I will review recent developments in the antenna subtraction method for higher-order calculations in QCD. In particular, I will illustrate the definition and applications of generalised antenna functions for final-state radiation at NNLO and present the first N${}^3$LO differential calculation performed entirely with antenna subtraction for jet production at electron-positron colliders. Finally, I will discuss how the extension of generalised antenna functions at N${}^3$LO will allow to tackle more complicated processes at this perturbative order.
