| Résumé : | The acoplanar photon pairs produced in the reaction e+e- →νν̄γγ are analysed in the 700 pb-1 of data collected by the ALEPH detector at centre-of-mass energies between 183 and 209 GeV. No deviation from the Standard Model predictions is seen in any of the distributions examined. The resulting 95% C.L. limits set on the anomalous QGCs, a0Z, acZ, a0W and a cW, are -0.012 < a0Z/ Λ2 < +0.019 GeV-2, -0.041 < a cZ/Λ2 < +0.044 GeV-2, -0.060 < a0W/Λ2 < +0.055 GeV -2, -0.099 < acW/Λ2 < +0.093 GeV-2, where Λ is the energy scale of the new physics responsible for the anomalous couplings. © 2004 Elsevier B.V.
