Description
We show how to substitute polarization vectors and spinors having discrete helicities for ones with continuous helicity angles which are suitable for numerical QCD computations. Using these polarizations one can avoid the time-consuming summation over all 2n helicity configurations in QCD observables. To extend this method to NLO, one needs modified subtraction terms which are discussed in this talk.
