Description

Abstract We present an automated generation of the subtraction terms for next-to-leading order QCD calculations in the Catani–Seymour dipole formalism. For a given scattering process with n external particles our Mathematica package generates all dipole terms, allowing for both massless and massive dipoles. The numerical evaluation of the subtraction terms proceeds with MadGraph, which provides Fortran code for the necessary scattering amplitudes. Checks of the numerical stability are discussed. Title of program: AutoDipole Catalogue Id: AEGO_v1_0 Nature of problem Computation of next-to-leading order QCD corrections to scattering cross sections, regularization of real emission contributions.
