Measurement of the $WZ$ diboson cross section at D0

Measurements of the $WZ$ diboson cross section are interesting both as a test of the standard model and as a potential indicator of new physics. We present a measurement of the $WZ$ cross section using $\ell\ell\ell \nu$ decays in $p\overline{p}$ collisions at $\sqrt{s}$ = 1.96 TeV using 3.6 fb$^{-1}$ of data taken at the D0 experiment at the Tevatron. Here, $\ell$ means either an electron or a muon.
