Using roughly 1 fb-1 of data, dilepton-plus-photon invariant mass distributions have been examined for an excess over the theoretical predictions. Having observed a good agreement between data and the standard model prediction we set 95% C.L. upper limits on the cross section times branching fraction (sigma x B) of the resonance Zgamma production.For the D0 Collaboration, ICHEP08 ProceedingsHigh Energy Physics - Experimenttext
