Z{gamma} production in p{bar p} collisions at {radical} (s) =1.8TeV and limits on anomalous ZZ{gamma} and Z{gamma}{gamma} couplings

We present a study of Z{gamma}+X production in p{bar p} collisions at {radical} (s) =1.8TeV from 97 (87)pb{sup {minus}1} of data collected in the ee{gamma} ({mu}{mu}{gamma}) decay channel with the D0 detector at Fermilab. The event yield and kinematic characteristics are consistent with the standard model predictions. We obtain limits on anomalous ZZ{gamma} and Z{gamma}{gamma} couplings for form factor scales {Lambda}=500GeV and {Lambda}=750GeV. Combining this analysis with our previous results yields 95{percent} C.L. limits {vert_bar}h{sub 30}{sup Z}{vert_bar}{lt}0.36, {vert_bar}h{sub 40}{sup Z}{vert_bar}{lt}0.05, {vert_bar}h{sub 30}{sup {gamma}}{vert_bar}{lt}0.37, and {vert_bar}h{sub 40}{sup {gamma}}{vert_bar}{lt}0.05 for a form factor scale {Lambda}=750GeV. {copyright} {ital 1998} {ital The American Physical Society}
