Abstract

We have measured the ZZγ and ZZγ couplings by studying 13.1 pb−1 of pp¯→Etγ+ X data at √s = 1.8 TeV with the Dø detector at the Fermilab Tevatron Collider. This is the first study of hadronic Zγ production in the neutrino decay channel. Combining this measurement with our previous results using Z→ee and μμ yields the most stringent 95% C.L. limits to date on anomalous couplings: |h30Z|<0.4, |h40Z|<0.06 (λ=750 GeV.
