Abstract: (arXiv)
We report on a search for the process ppˉγ+W/Zp\bar{p}\to \gamma+W/Z with W/ZqqˉW/Z\to q\bar{q} in events containing two jets and a photon at the center-of-mass energy s=1.96\sqrt{s}=1.96 TeV, using 184 pb1^{-1} of data collected by the CDF II detector. A neural network event selection has been developed to optimize the rejection of the large QCD production background/ it is shown that this method gives a significant improvement in both signal-to-noise ratio and signal sensitivity, as compared with an event selection based on conventional cuts. An upper limit is presented for the γ+W/Z\gamma+W/Z production cross section with the WW and ZZ decaying hadronically.
