Abstract We report on a search for W/Z hadronic decays in photon events. The study is based on 184 pb-1 of CDF Run II data collected with a low pt photon trigger. A neural network technique is employed to select the diboson candidates. The limit is evaluated using a fully Bayesian approach taking into account all the systematic uncertainties. The 95% confident level upper limit on Sigma (ppbar -> Wγ) * BR (W -> qq') + Sigma (ppbar -> Zγ) * BR (Z -> qqbar) is set to 54 pb, consistent with the NLO Standard Model prediction of 20.5 pb.
