DESCRIPTION:Speakers: MATTEO MARCOLI (University of Durham)\n\nIn this tal
 k\, 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 subt
 raction method. In particular\, I will highlight progress aimed at automat
 ion and computational efficiency at NNLO\, especially for high-multiplicit
 y processes. I will introduce generalized antenna functions for final-stat
 e radiation and discuss their phenomenological applications for the calcul
 ation of the NNLO correction to four-jet production at electron-positron c
 olliders. I will also present the first N3LO differential calculation perf
 ormed 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.\n\nhttps://indico.global/event/17273/
