Physical Review D 71,9 (2005) 091105(R);
We present a search for ZZ and ZW vector boson pair production in p (p) over bar collisions at root z = 1.96 TeV using the leptonic decay channels ZZ -> ll nu nu, ZZ -> lll(')l('), and ZW -> lll(')v. 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 plus ZW production, compared to the standard model prediction of 5.0 +/- 0.4 pb.
