Sector-improved residue subtraction: Improvements and Applications
Arnd Behring🇩🇪 · Michal Czakon🇩🇪 · Rene Poncelet🇩🇪
Abstract
We discuss two recent developments of the sector-improved residue subtraction scheme for handling real radiation at NNLO in QCD. We present a new phase space construction which minimizes the number phase space configurations for subtraction terms and we rederive the four-dimensional formulation of the scheme.
