Abstract

We present results from a search for WZ production with subsequent decay to â.,"Îâ.,"â€â., "Ââ€(â.," and â.,"â€=e or Î) using 0.30fb-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 4.5-2.6+3.8pb, 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<Î"ÎZ<2.4 for form factor scale Î=1TeV, and -0.48<Î Z<0.48 and -0.49<Î"g1Z<0. 66 for Î=1.5TeV. © 2005 The American Physical Society.
