Helicity Amplitudes for Order alphas Production of W+W-, W+-Z, ZZ, W+-gamma, or Z gamma Pairs at Hadron Colliders

Abstract

\noindent We present the one-loop QCD corrections to the helicity amplitudes for the processes $q\qb \to W^+ W^-,\ Z \, Z,\ W^\pm Z, \ W^\pm \gamma$, or $Z \gamma$, 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.
