Query: Evidence for Diboson Production in the Lepton plus Heavy Flavor Jets
  Final State at CDF   This thesis presents the evidence, at 3.08 sigma, for the associate
production of massive vector bosons (W and Z) in a final state with one lepton,
MET and HF-tagged jets, measured with the complete CDF II dataset (9.4fb^-1 of
data). The signals, both inclusive diboson production and WW vs WZ/ZZ
separately, were extracted from the invariant mass distribution,
M_inv(jet1,jet2), of single and double HF-tagged jet pairs. For single-tagged
events the b quark vs c quark discrimination was obtained by using a
bi-dimensional distribution M_inv(jet1,jet2) vs a flavor-serapator NN. The
results, consistent with the SM prediction, confirm the CDF capability of
identify a small signal in this challenging final state. In particular we also
report the previous version of this analysis, performed with a dataset of
7.5fb^-1 that was the first evidence of diboson production in lnu+HF final
state at a hadron collider. Beyond the pure testing of SM predicted processes,
several of the techniques developed for this thesis were also applied to the WH
search at CDF, with a relevant improvement of the sensitivity to this process.
