Two-loop helicity amplitudes for the production of two off-shell electroweak bosons in quark-antiquark collisions
Abstract
Knowledge of two-loop QCD amplitudes for processes qq'→V1V2→(l1$$\overline{l}$$'1)(l2$$\overline{l}$$'2) is important for improving the theoretical description of four-lepton production in hadron collisions. In this paper we compute these helicity amplitudes for all intermediate vector bosons, V 1 V 2 = γ * γ *, W + W -, ZZ, W ± Z, W ± γ *, including off-shell effects and decays to leptons.
