Abstract
We present a search for and production in final states that contain a charged lepton (electron or muon) and at least two jets, produced in collisions at the Fermilab Tevatron, using data corresponding to of integrated luminosity collected with the CDF II detector. Diboson production in this decay channel has yet to be observed at hadron colliders due to the large single plus jets background. An artificial neural network has been developed to increase signal sensitivity, as compared with an event selection based on conventional cuts. We set a 95% confidence level upper limit of , which is consistent with the standard model next-to-leading-order cross section calculation for this decay channel of .
