Search for $WW$ and $WZ$ production in charged lepton-neutrino plus dijet final state at CDF

We present a search for $WW$ and $WZ$ production in charged lepton-neutrino plus dijet final states produced in $p \bar{p}$ collisions with $\sqrt{s}=1.96$~TeV at the Fermilab Tevatron, using approximately 1.1 fb$^{-1}$ of data accumulated with the CDF II detector. This channel is yet to be observed in hadron colliders due to the large single $W$ plus jets background. However, this decay mode has a much larger branching fraction than the cleaner fully leptonic mode making it more sensitive to anomalous triple gauge couplings which typically manifest themselves at higher transverse $W$ momenta. Because the final state is topologically similar to associated production of a Higgs boson with a $W$ boson, the techniques developed in this analysis are also applicable in that search.
