Search for particles decaying into $Z\gamma$ at D0

Abstract

Results on the search for particles decaying into Zgamma to llgamma are presented. 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.
