Alternative subtraction scheme using Nagy Soper dipoles

Understand

We present an alternative subtraction scheme for the treatment of infrared divergences in NLO QCD calculations.

• In this scheme, the number of transformations is greatly reduced with respect to the standard subtraction scheme by Catani and Seymour.
• We discuss the general setup of the scheme as well as first applications to NLO processes at hadron and lepton colliders.
