One-loop amplitudes for e +e - -+ overlineqoverlineQQ
Abstract
We present the one-loop helicity amplitudes for processes involving a vector boson V ( V = W, Z, or y*) and four massless quarks, 0 → V overlineqq overlineQQ , where V couples to a massless lepton pair. These amplitudes are required for next-to-leading order Oαs3) numerical programs for four jet production at e+e- colliders, for W, Z or Drell-Yan production in association with two jets at hadron colliders, and for three jet production in deeply inelastic scattering experiments. We obtained the amplitudes presented here by using their analytic properties to constrain their form.
