Abstract
We present a measurement of the Zγ production cross section and limits on anomalous ZZγ and Zγγ couplings for form-factor scales of Λ =750 and 1000 GeV. The measurement is based on 138 (152) candidates in the eeγ (μ μ γ) final state using 320(290) pb-1 of pp‾ collisions at vs=1.96 TeV. The 95% C.L. limits on real and imaginary parts of individual anomalous couplings are |h10,30Z|< 0.23, |h20,40Z|< 0.020, |h10,30γ|< 0.23, and |h20,40γ|< 0.019 for Λ=1000 GeV.
