Search for diboson production in final states containing missing transverse energy and $b$-quark jets

Diboson production in hadronic final states has been recently observed at the Tevatron in several channels. The dominant contribution to this process is $WW$ production with lower cross section contributions from $WZ$ and $ZZ$. Imposing the additional requirement that the observed hadronic jets are consistent with having originating from $b$-quark decays drastically reduces the contribution from $WW$ and enhances $WZ/ZZ$ contributions. Here we present a search for $WZ/ZZ$ in events with missing transverse energy and $b$-quark jets at CDF. The final state being measured is very similar to that obtained from associated Higgs production where the Higgs decays to two $b$-quarks and evidence for it is an important step towards a potential Higgs discovery.
