Update on vector boson pair production at hadron colliders - art. no. 113006

We present numerical results (including full one-loop QCD corrections) for the processes <p(p)over bar> and pp --> W+ W-, W+/- Z/gamma* and Z/gamma* Z /gamma* followed by the decay of the massive vector bosons into leptons. In addition to their intrinsic importance as tests of the standard model, the se processes are also backgrounds to conjectured non-standard model process es. Because of the small cross sections at the Fermilab Tevatron, full expe rimental control of these backgrounds will be hard to achieve. This accentu ates the need for up-to-date theoretical information. A comparison is made with earlier work and cross section results are presented for pp collisions at root s = 2 TeV and pp collisions at root s = 14TeV. Practical examples of the use of our calculations are presented. [S0556-2821(99)01323-5].
