Abstract

We have measured the ZZ_γ and ZZ_γ couplings by studying 13.1 pb⁻¹ of pp^¯→E_tγ+ X data at √s = 1.8 TeV with the Dø detector at the Fermilab Tevatron Collider. This is the first study of hadronic Z_γ 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: |h₃₀^Z|<0.4, |h₄₀^Z|<0.06 (λ=750 GeV.
