摘要
We present a study of the dijet invariant mass distribution for the reaction (p) over barp -> 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 (p) over barp -> 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.
