Abstract
 We report the first observation of the associated production of a W boson and a Z boson. This result is based on 1.1  fb-1 of integrated luminosity from pp̅ collisions at √s=1.96  TeV collected with the CDF II detector at the Fermilab Tevatron. We observe 16 WZ candidates passing our event selection with an expected background of 2.7±0.4 events. A fit to the missing transverse energy distribution indicates an excess of events compared to the background expectation corresponding to a significance equivalent to 6 standard deviations. The measured cross section is σ(pp̅ →WZ)=5.0-1.6+1.8   pb, consistent with the standard model expectation.
