Observation of Diboson Production in a Semileptonic Decay at CDF

We present the first observation of WW+WZ production in the channel with an identified lepton and two jets in 2.7 fb$^{-1}$ of integrated luminosity collected with the CDF II detector in $p\bar{p}$ collisions at $\sqrt{s} = 1.96$ TeV. The signal is separated from the large background using matrix element calculations and is observed with a significance of 5.4$σ$. The WW+WZ production cross section is measured to be $17.7 \pm 3.1$(stat)$\pm 2.4$(sys) pb, in good agreement with standard model predictions. A complimentary measurement using a fit to the dijet mass is also presented.

Diboson Measurements at the Tevatron

We present a summary of recent WW, WZ, and ZZ measurements carried out in $\sqrt{s} = 1.96$ TeV at the Tevatron. The observation of rare ZZ events and the precise measurement of the WW cross section in fully leptonic decay modes are described. Results in semi-leptonic decay modes where one boson decays to two quarks are also presented. The measurements described are all in good agreement with the Standard Model and are relevant to searches for the Higgs boson at the Tevatron.
