A measurement of the WZ and ZZ production cross sections using leptonic
final states in 8.6 fb$^{-1}$ of $p\bar{p}$ collisions    [PDF]

D0 Collaboration

We study the processes $p\bar{p} \rightarrow WZ \rightarrow
\ell\nu\ell^+\ell-$ and $p\bar{p} \rightarrow ZZ \rightarrow
\ell^+\ell^-\nu\bar{\nu}, where $\ell$ = $e$ or ${\mu}$. Using 8.6 fb$^{-1} of
integrated luminosity collected by the D0 experiment at the Fermilab Tevatron
collider, we measure the $WZ$ production cross section to be
4.50$^{+0.63}_{-0.66} pb which is consistent with, but slightly above a
prediction of the standard model. The ZZ cross section is measured to be 1.64
$\pm$ 0.46 pb, in agreement with a prediction of the standard model.
Combination with an earlier analysis of the $ZZ \rightarrow
\ell^+\ell^-\ell^+\ell^-$ channel yields a $ZZ$ cross section of
1.44$^{+0.35}_{-0.34}$ pb.
