Abstract
We present a search for ZZ and ZW vector boson pair production in pp̅ collisions at √s =1.96 TeV using the leptonic decay channels ZZ→llνν, ZZ→lll′ l′, and ZW→lll′ν. In a data sample corresponding to an integrated luminosity of 194 pb-1 collected with the Collider Detector at Fermilab, 3 candidate events are found with an expected background of 1.0±0.2 events. We set a 95% confidence level upper limit of 15.2 pb on the cross section for ZZ and ZW production, compared to the standard model prediction of 5.0±0.4 pb.
