We present the first observation of the Z[gamma] →[nu]{bar [nu]}[gamma] process at the Tevatron at 5.1 standard deviations significance, based on 3.6 fb−1 of integrated luminosity collected with the D0 detector at the Fermilab Tevatron p{bar p} Collider at √s = 1.96 TeV. The measured Z[gamma] cross section multiplied by the branching fraction of Z → {nu}{bar {nu}} is 32 ± 9(stat. + syst.) ± 2(lumi.) fb for the photon E{sub T} > 90 GeV. It is in agreement with the standard model prediction of 39 ± 4 fb. We set the most restrictive limits on anomalous trilinear Z[gamma][gamma] and ZZ[gamma] gauge boson couplings at a hadron collider to date, with three constraints being the world's strongest.

The authors present a measurement of the Z[gamma] production cross section and limits on anomalous ZZ[gamma] and Z[gamma][gamma] couplings for form-factor scales of [Lambda] = 750 and 1000 GeV. The measurement is based on 138 (152) candidate events in the ee[gamma] ([mu][mu][gamma]) final state using 320 (290) pb−1 of p{bar p} collisions at √s = 1.96 TeV. The 95% C.L. limits on real and imaginary parts of individual anomalous couplings are

The authors performed a direct search for the anomalous ZZ[gamma] and Z[gamma][gamma] couplings by studying p[anti p][yields][ell][ell][gamma]+ X, ([ell]= e, [mu]) events at[radical]s= 1.8 TeV with the D0 detector at the Fermilab Tevatron Collider. A fit to the transverse energy spectrum of the photon in the signal events, based on the data set corresponding to an integrated luminosity of 14.3 pb[sup[minus]1] (13.7 pb[sup[minus]1]) for the electron (muon) channel, yields the following 95% confidence level limits on the anomalous CP-conserving ZZ[gamma] couplings:[vert-bar]h[sub 30][sup Z][vert-bar]
