Received 13 July 2005; published 6 January 2006

We present a study of the dijet invariant mass distribution for the reaction [overline p]p-->two jets+gamma+X, at a center of mass energy of 1.8 TeV, using data collected by the CDF experiment. We compare the data to predictions for the production of a photon with two jets, together with the resonant processes [overline p]p-->W/Z+gamma+X, in which the W and Z bosons decay hadronically. A fit is made to the dijet invariant mass distribution combining the nonresonant background and resonant processes. We use the result to establish a limit for the inclusive production cross section of W/Z+gamma with hadronic decay of the W and Z bosons.
