Production of WZ events in $p\bar p$ collisions at $\sqrt{s}$=1.96 TeV and limits on anomalous WWZ couplings
We present results from a search for WZ production with subsequent decay to l nu l'-bar l' (l and l'=electron or muon) using 0.30 fb^(-1) of data collected by the DO experiment between 2002 and 2004 at the Tevatron. Three events with WZ decay characteristics are observed. With an esti...

| description | We present results from a search for WZ production with subsequent decay to l nu l'-bar l' (l and l'=electron or muon) using 0.30 fb^(-1) of data collected by the DO experiment between 2002 and 2004 at the 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 (+3.8 -2.6) 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_Z < 2.4 for form factor scale Lambda = 1 TeV, and -0.48 < lambda_Z < 0.48 and -0.49 < Delta g_1^Z < 0.66 for Lambda = 1.5 TeV. |

Three events with WZ decay characteristics are observed.
