Search for $WZ$ Production at the Tevatron

We present a search for $WZ$ production using $\approx$800 pb$^{-1}$ of data accumulated with the CDF~II detector. Our event selection criteria of three charged leptons and missing transverse energy is sensitive to $p\bar{p} \rightarrow WZ \rightarrow \ell\nu\ell\ell$ production. The main background sources to this channel are dilepton final states from Drell-Yan and top quark production with a hadronic jet misidentified as a lepton.
