SARGE: An algorithm for generating QCD-antennas

We present an algorithm to generate any number of random massless momenta in phase space, with a distribution that contains the kinematical pole structure that is typically found in multi-parton QCD-processes. As an application, we calculate the cross-section of some e+e−→partons processes, and compare SARGEʹs performance with that of the uniform-phase space generator RAMBO.
