Abstract
We present the one-loop QCD corrections to the helicity amplitudes for the processes q q → W +W −, Z Z, W ±Z, W ±γ, or Zγ , including the subsequent decay of each massive vector boson into a pair of leptons. We also give the corresponding tree-level amplitudes with an additional gluon radiated off the quark line. Together, these amplitudes provide all the necessary input for the calculation of the next-to-leading order QCD corrections to the production of any electroweak vector boson pair at hadron colliders, including the full spin and decay-angle correlations.
