The authors present the results of the first search for a new particle X produced in p{bar p} collisions at √s = 1.96 TeV and subsequently decaying to Z[gamma]. The search uses 0.3 fb−1 of data collected with the D0 detector at the Fermilab Tevatron Collider. They set limits on the production cross section times the branching fraction [sigma](p{bar p} → X) x B(X → Z[gamma]) that range from 0.4-3.5 pb at the 95% C.L. for X with invariant masses between 100 and 1000 GeV/c2 over a wide range of X decay widths.

The authors present a study of the dijet invariant mass distribution for the reaction {bar p}p → 2 jets+? + X, at a center of mass energy of 1.8 TeV, using data collected by the CDF experiment. They compare the data to predictions for the production of a photon with two jets, together with the resonant processes {bar p}p → W/Z +? + 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. They use the result to establish a limit for the inclusive production cross section of W/Z +? with hadronic decay of the W and Z bosons.

The authors present a study of the dijet invariant mass distribution for the reaction {bar p}p → 2 jets+[gamma] + X, at a center of mass energy of 1.8 TeV, using data collected by the CDF experiment. They compare the data to predictions for the production of a photon with two jets, together with the resonant processes {bar 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 non-resonant background and resonant processes. They 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.

Z[degrees] bosons have been produced by collisions of longitudinally polarized electrons with unpolarized positrons at the SLAC Linear Collider and their decays have been recorded by the SLD experiment. We present preliminary measurements of the properties of the resulting Z[degrees] decays into multi-hadronic final states. We find good agreement with the predictions of perturbative QCD and fragmentation models.
