Description
We present the CDF measurement of the diboson WW and WZ production cross section in a final state consistent with leptonic W decay and jets originating from heavy flavor quarks, based on the full Tevatron Run II dataset.
The analysis of the di-jet invariant mass spectrum allows the observation of 3.7 sigma evidence for the combined
production processes of either WW or WZ bosons. The different heavy flavor decay pattern of the W and Z bosons
and the analysis of the secondary-decay vertex properties allow to independently measure the WW and WZ production
cross section in a hadronic final state. The measured cross sections are consistent with the standard model
predictions and correspond to signal significances of 2.9 and 2.1 sigma for WW and WZ production, respectively.
