• We present results from a search for WZ production with subsequent decay to l{nu}l{sup '}l{sup '} (l and l{sup '}=e or {mu}) using 0.30 fb{sup -1} of data collected by the D0 experiment between 2002 and 2004 at the Fermilab Tevatron. Three events with WZ decay characteristics are observed. With an estimated background of 0.71{+-}0.08 events, we measure the WZ production cross section to be 4.5{sub -2.6}{sup +3.8} pb, with a 95% C.L. upper limit of 13.3 pb. The 95% C.L. limits for anomalous WWZ couplings are found to be -2.0<{delta}{kappa}{sub Z}<2.4 for form factor scale {lambda}=1 TeV, and -0.48<{lambda}{sub Z}<0.48 and -0.49<{delta}g{sub 1}{sup Z}<0.66 for {lambda}=1.5 TeV.
