Leptonic Signals from off-shell Z Boson Pairs at Hadron Colliders

Abstract
We study the gluon fusion into pairs of off-shell Z bosons and their subsequent decay into charged lepton pairs at hadron colliders. We do not restrict the intermediate state Z bosons to the narrow width approximation but allow for arbitrary invariant masses. We compare the strength of this process with the known leading order results for q qbar -> Z Z -> 4 l and for g g -> H -> Z Z -> 4 l .
