Abstract: (arXiv)

Diboson production (

WW+WZ+ZZ

) has been observed at the Tevatron in hadronic decay modes dominated by the

WW

process. This paper describes the measurement of the cross section of

WZ

and

ZZ

events in final states with large \mett and using

b

-jet identification as a tool to suppress

WW

contributions. Due to the limited energy resolution, we cannot distinguish between partially hadronic decays of

WZ

and

ZZ

, and we measure the sum of these processes. The number of signal events is extracted using a simultaneous fit to the invariant mass distribution of the two jets for events with two

b

-jet candidates and events without two

b

-jet candidates. We measure a cross section

\sigma(p\bar{p}\to WZ,ZZ) = 5.8^{+3.6}_{-3.0}

pb, in agreement with the standard model.
