Abstract:
We present a study of the dijet invariant mass distribution for the reaction p anti-p --> 2 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 anti-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 non-resonant 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.
