Abstract
We present a study of Zγ+X production in pp̅ collisions at √s=1.8TeV from 97 (87)pb−1 of data collected in the eeγ (µµγ) 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 ZZγand Zγγ couplings for form factor scales Λ =500GeV and Λ =750GeV. Combining this analysis with our previous results yields 95% C.L. limits |h30Z|<0.36, |h40Z|<0.05, |h30Υ|<0.37, and |h40Υ|<0.05 for a form factor scale Λ =750GeV.
