Measurement of $WZ$ 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 the fully leptonic decay mode of $lll\nu$ final states in $p-\overline{p}$ collisions at $\sqrt{s}$ = 1.96 TeV with 5 fb$^{-1}$ of data taken at the D{\O} experiment at the Tevatron. This measurement includes, for the first time, the ICR (Inter-Crytostat Region) for the electron acceptance.
