An alternative subtraction scheme for NLO calculations — •Tania Robens¹ and Cheng Han Chung² — ¹IKTP, TU Dresden — ²RWTH Aachen University

We present a new subtraction scheme for next-to-leading order QCD calculations, where the momentum mapping and the splitting functions have been derived in the context of an improved parton shower formulation. A main advantage of our scheme is the significantly reduced number of momentum mappings in the subtraction terms compared to standard schemes. We discuss the general setup as well as examples for several processes.
