Observation of WZ production

Abstract:

We report the first observation of the associated production of a W boson and a Z boson. This result is based on 1.1fb-1 of integrated luminosity from pp̄ collisions at s=1.96TeV 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 e...
