Abstract
The study of associated boson production in the final state with a lepton, neutrino, and a bb-pair is important since the event topology of this process is the same as expected for associated production of a W and the Standard Model light-Higgs boson. Thus, the search for boson production can be considered as a preliminary step towards the Higgs discovery. Here we present a search for WZ/ZZ in events with a lepton, missing transverse energy, and b-quark jets. Besides looking at the sample where two exclusive jets are found, we investigate the sample with 3 jets which contains 40% of the signal events. In this sample the invariant mass of the two ET-leading jets would normally be chosen to signal the Z boson. We describe an alternative procedure to reconstruct the Z-invariant mass in this sample. This procedure exploits the information carried by the third jet in the sample.
