We study the processes pp- → WZ→ l± vl+ l- and pp-→ZZ →l+ l- vv-, where l = e or μ. Using 8.6 fb-1 of integrated luminosity collected by the D0 experiment at the Femilab Tevatron collider, we measure the WZ production cross section to be 4.50 -0.66 pb which is consistent with, but slightly larger than, the prediction of the standard model. The ZZ cross section is measured to be 1.64± 0.46 pb, in agreement with a prediction of the standard model. Combination with an earlier analysis of the ZZ→ l+ l- l+ l- channel yields a ZZ cross section of 1.44 +0.35 -0.34 pb.
