The measured Zγ production cross section multiplied by the branching fraction of Z→νν-bar is 32±9(stat+syst)±2(lumi)  fb for the photon E(T)>90  GeV. It is in agreement with the standard model prediction of 39±4  fb. We set limits on anomalous trilinear Zγγ and ZZγ gauge boson couplings, most of which are the most restrictive to date.Article10.1103/PhysRevLett.102.201802openAccess
