Generating QCD antennas

/ Abstract
Abstract. An extension of the SARGE algorithm of van Hameren, Kleiss and Draggiotis is introduced, which includes the incoming momenta in the kinematical pole structure of the density with which the momenta are generated. The algorithm is compared with RAMBO in the integration of QCD amplitudes in the SPHEL approximation, and the computing times are extrapolated to those for the calculation with exact matrix elements.
